10. The Diyne Reaction of 3,3?-Bis(phenylethynyl)-2,2?-bithiophene Derivatives via Rhodium Complexes: A Novel Approach to Condensed Benzo[2,1-b:3,4b’]dithiophenes

The syntheses of benzo-fused benzo[2,1-b:3,4-b’]dithiophenes 1 and benzo[2,1-b:3,4-b’:5,6-c?]trithiophenes 2 are described. The treatment of easily available 3,3?-bis(phenylethynyl)-2,2?-bithiophene derivatives 5a and 6 (via PdII-catalyzed alkynylation of the corresponding 3,3?-dibromo-2,2?-bithiophenes; see Scheme 1) with chlorotris(triphenylphosphine)rhodium(I) yields the corresponding cyclic rhodium complexes 7 (Scheme 2) which smoothly react with acetylenes and sulfur to give 1 and 2 in good yields (Schemes 3-5).

We¡¯ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, the role of 6287-82-7, and how the biochemistry of the body works.Formula: C8H4Br2S

In homogeneous catalysis, the catalyst is in the same phase as the reactant. The number of collisions between reactants and catalyst is at a maximum.In a patent, 6287-82-7, name is 2,3-Dibromobenzo[b]thiophene, introducing its new discovery. Formula: C8H4Br2S

Ligand cooperation in the formal hydrogenation of N2O using a PCsp2P iridium pincer complex

A new PCcarbeneP pincer ligand with 2,3-benzo[b]thiophene linkers connecting the flanking dialkyl phosphine donors to the central carbene can be attached to Ir(I). The chloro derivative reacts with N2O with loss of N2 to form an iridaepoxide species by addition of an oxygen atom to the Ir=C linkage. This compound reacts with H2 to afford the oxidative addition product, in which the hydride ligands are trans to the Ir-O bond. Heating this dihydride results in slow release of H2O; kinetic and spectroscopic studies show that conversion of the dihydride to its isomer, in which the hydrides are cis to the Ir-O bond, is required for H2O elimination to take place. Together, these reactions constitute the stoichiometric conversion of N2O and H2 to N2 and H2O; further mechanistic studies suggest ways to make the system catalytic.

Cope Rearrangements in the Benzothiophene Series

The inability to observe Cope rearrangement products at elevated temperatures for diethyl alpha-allyl-2-naphthalenemalonate (1) and diethyl alpha-allyl-9-phenanthrenemalonate (2) does not extend to the analogous systems resulting from replacement of the aromatic units by 2- and 3-benzothiophene nuclei.Thermal rearrangement of diethyl alpha-allyl-3-benzothiophenemalonate (5) at 215-255 deg C for 11 h produces the expected Cope rearrangement product diethyl 2-allyl-3-benzothiophenemalonate (10) (8percent) accompanied by trans- and cis-ethyl 2,3-dihydro-1-(ethoxycarbonyl)-1H-benzocyclopentathiophene-2-acetate (9a) (10percent) and (9b) (5percent), respectively.The structure elucidation of 10, 9a, and 9b was done by spectroscopy.The attempted structure verification of 10 by an independent route gave diethyl 2-(1-propenyl)-3-benzothiophenemalonate (12) which when heated at 230-240 deg C for 18 h gave 1-carbethoxy-2-hydroxy-3-methyldibenzothiophene (16) as a major product.Similar results were observed with 2-substituted analogues of 5, both diethyl 3-allyl-2-benzothiophenemalonate (24) and ethyl 1,2-dihydro-3-(ethoxycarbonyl)-3H-benzocyclopentathiophene-2-acetate (25) being formed.In this case the structure of 24 was verified by synthesis.An extension of this involved a study of thermal rearrangement of analogous compound ethyl alpha-allyl-alpha-cyano-3-benzothiopheneacetate (30).Thermal rearrangement of 30 at 235-245 deg C for 8 h gave the expected Cope rearrangement product ethyl alpha-cyano-2-allyl-3-benzothiopheneacetate (32) (6percent) along with an unexpected diastereomeric mixture of 1-cyano-1-(ethoxycarbonyl)-2-methyl-2,3-dihydro-1H-benzocyclopentathiophenes (33) (18percent).Speculative mechanistic considerations are offered regarding the mode of transformation of 12 to 16 and 32 to 33.

Large geometrical structure changes of photochromic diarylethenes upon photoirradiation

Photochromic diarylethene derivatives having phenylethynyl and pent-1-ynyl groups at the reactive carbons have been synthesized. These ethynyl groups enhance the cycloreversion quantum yields of diarylethenes without affecting the absorption maxima and the absorption coefficients of the closed-ring isomers. The derivatives exhibited large geometrical structural changes in the photoisomerization process.

Design of reversible multi-electron redox systems using benzochalcogenophenes containing aryl and/or ferrocenyl fragments

2,3-Disubstituted benzo[b]thiophenes, 1,3-disubstituted benzo[c]thiophenes, and 1,3-disubstituted benzo[c]selenophene have been systematically and selectively synthesized from benzo[b]thiophene or phthaloyl dichloride as a starting material, respectively. Characterization of the molecules was performed by physical and spectroscopic means and X-ray crystallographic analyses. The cyclic voltammograms of the chalcogenophene derivatives containing aryl fragments showed well-defined reversible both anodic and cathodic steps derived from the unusually stable 5pi chalcogenophene radical cations and 7pi chalcogenophene radical anions. The cyclic voltammograms of the novel chalcogenophene derivatives containing ferrocenyl fragments showed a well-defined reversible cathodic step derived from the unusually stable 7pi chalcogenophene radical anions and two distinct reversible anodic steps derived from ferrocenium cations separated from each other by a thiophene-heterocycle. The radical character of several novel 7pi chalcogenophene radical anions was measured by ESR spectroscopy.

Transition-metal-free decarboxylative bromination of aromatic carboxylic acids

Methods for the conversion of aliphatic acids to alkyl halides have progressed significantly over the past century, however, the analogous decarboxylative bromination of aromatic acids has remained a longstanding challenge. The development of efficient methods for the synthesis of aryl bromides is of great importance as they are versatile reagents in synthesis and are present in many functional molecules. Herein we report a transition metal-free decarboxylative bromination of aromatic acids. The reaction is applicable to many electron-rich aromatic and heteroaromatic acids which have previously proved poor substrates for Hunsdiecker-type reactions. In addition, our preliminary mechanistic study suggests that radical intermediates are not involved in this reaction, which is in contrast to classical Hunsdiecker-type reactivity. Overall, the process demonstrates a useful method for producing valuable reagents from inexpensive and abundant starting materials.

Enhanced performance of benzothieno[3,2-b]thiophene (BTT)-based bottom-contact thin-film transistors

Three new benzothieno[3,2-b]thiophene (BTT; 1) derivatives, which were end-functionalized with phenyl (BTT-P; 2), benzothiophenyl (BTT-BT; 3), and benzothieno[3,2-b]thiophenyl groups (BBTT; 4; dimer of 1), were synthesized and characterized in organic thin-film transistors (OTFTs). A new and improved synthetic method for BTTs was developed, which enabled the efficient realization of new BTT-based semiconductors. The crystal structure of BBTT was determined by single-crystal X-ray diffraction. Within this family, BBTT, which had the largest conjugation of the BTT derivatives in this study, exhibited the highest p-channel characteristic, with a carrier mobility as high as 0.22 cm2 V-1 s-1 and a current on/off ratio of 1¡Á10 7, as well as good ambient stability for bottom-contact/bottom-gate OTFT devices. The device characteristics were correlated with the film morphologies and microstructures of the corresponding compounds. Copyright
