(Chemical Equation Presented) A photochemical active triangle terarylene was synthesized and the photochromic behavior was investigated. Its photochromic reactivity can be strongly suppressed by selected oxidization of the sulfur atoms in the molecules. Reactivated photochromic reactivity was obtained by deoxidization of the S,S-dioxide moieties. The suppressed photoactivity of the oxidation state was attributed to the stronger intramolecular hydrogen bonding interactions.

Various tetrayne systems were converted under dual gold-catalyzed conditions. For symmetric tetraalkynyl-substituted thiophenes, bearing two alkyl-substituted alkynes and two terminal alkyne units, bidirectional cyclizations led to the efficient formation of dibenzothiophene systems. In all cases, selective CH activation of the C?H bond of the alkyl substituent was observed leading to cyclopentane moieties annelated to the newly formed aromatic cores. If two thiophene moieties were tethered over the attached non-terminal alkynes, depending on the length of the connecting alkyl tether, either bidirectional processes or tandem processes can be addressed leading to interesting molecular structures, such as spiro compounds or isolated benzothiophenes connected by a C?C bond. Other electron-rich heterocycles also reacted. While the reactions even worked for some mixed systems, other cases only delivered the products of a mono-cyclization.

Phosphole-containing pi-systems have emerged as building blocks with enormous potential as electronic materials because of the tunability of the phosphorus center. Among these, asymmetric P-bridged trans-stilbenes are still rare, and here an elegant and efficient synthesis toward such fluorescent molecular frameworks is described. Fine-tuning of the photophysical properties is attempted by enforcing the planarization of the phosphorus tripod and thus increasing the interaction between the phosphorus lone pair and the pi-system. The electronic structure of the pi-conjugated frameworks is analyzed with NMR, UV-vis and fluorescence spectroscopy, and time-dependent density functional theory (TD-DFT) calculations.

The first series of oxcarbazepine analogues, starting from readily-available materials and through a high-yielding five-step sequence based on palladium catalysis, is reported. The so-obtained compounds incorporate not only a variety of substituents in both of the aryl rings comprising the framework of an oxcarbazepine, but also involve the more challenging palladium-catalysed coupling of a number of heteroaromatic substrates. The addition of small amounts of water in some of the metal-catalysed processes showed a beneficial effect, highly increasing the selectivity of such reactions.

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.

I am very proud of our efforts over the past few months and hope to 6287-82-7 help many people in the next few years. SDS of cas: 6287-82-7

Deprotonation of benzothiophene-derived alkynyl imine 11 with lithium diisopropylamide (LDA) and subsequent transmetalation with ZnCl2 etherate furnished azepine 12 upon aqueous workup. Similarly, alkynyl benzaldimine la gave a mixture of benzazepine 13 and naphthylamine 14. Allylic benzonitriles 15a,b reacted to produce naphthylamine 16 upon deprotonation with LDA at room temperature. In an analogous manner, imino benzonitrile 17 may be converted into 4-amino isoquinoline 18 by means of an intramolecular nucleophilic attack on the nitrile function upon treatment with LDA. The allylic benzonitriles 19a,b were prepared by LDA treatment of alkynyl imine 11. They were further converted to amino dibenzothiophene 20 by LDA deprotonation and aqueous workup. These various transformations represent the key steps of a multistep reaction cascade, which was previously postulated on the basis of quantum chemical calculations. Thus, all features of this complex rearrangement mechanism could now be confirmed experimentally. DFT calculations support the lower reactivity of zinc species in the ring-opening step compared to the lithium intermediates. All new compounds were completely characterized by spectroscopic data, including X-ray diffraction studies for the key compounds 12, 19a, and 20.
