Late Stage Functionalization of Secondary Amines via a Cobalt-Catalyzed Electrophilic Amination of Organozinc Reagents

A general preparation of polyfunctional hydroxylamine benzoates from the corresponding secondary amines is reported. This convenient synthesis allows the setup of a late-stage functionalization of various secondary amines, including pharmaceuticals and peptidic derivatives. Thus, a cross-coupling of hydroxylamine benzoates with various alkyl-, aryl-, and heteroaryl-zinc chlorides in the presence of 5 mol % CoCl2 (25 C, 2 h) provides a range of polyfunctional tertiary amines. This method was used to prepare penfluridol and gepirone.

Catalytic [2 + 2 + 2] cycloaddition of benzothiophene dioxides with alpha,omega-diynes for the synthesis of condensed polycyclic compounds

A Rh-catalyzed intermolecular [2 + 2 + 2] cycloaddition of the 2,3-double bond of benzothiophene dioxides with alpha,omega-diynes gave sulfone-containing cycloadducts in high yields. This is the first example of a catalytic [2 + 2 + 2] cycloaddition that uses the 2,3-double bond of a heterole as an ene moiety. The consecutive reaction of benzodithiophene tetraoxide with 2,3-naphthylene-tethered 1,7-diyne gave an 11-ring condensed polycyclic compound in one pot.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. Recommanded Product: 4923-87-9, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 4923-87-9, in my other articles.

Visible light photocatalytic synthesis of benzothiophenes

The photocatalytic reaction of o-methylthio-arenediazonium salts with alkynes yields substituted benzothiophenes regioselectively through a radical annulation process. Green light irradiation of eosin Y initiates the photoredox catalysis. The scope of the reaction was investigated by using various substituted diazonium salts and different alkynes.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.SDS of cas: 63675-74-1, you can also check out more blogs about63675-74-1

Synthesis of 5,7,12,14-tetraarylpentacenes from pentacene-5,7,12,14-tetrone and characterisation of the tetrol intermediates

Pentacene has excellent semi-conducting properties but its practical use in organic thin-film transistors (OTFTs) has some drawbacks caused by its sensitivity to oxygen and low solubility. In order to overcome these problems one can introduce substituents on the ring system. In this context, we are investigating the possibility of introduction of aryl substituents on the pentacene backbone. 5,7,12,14-Tetraaryl-substituted pentacenes are described in this article. They have been prepared from the 5,7,12,14-aryl-substituted pentacene-5?,7?,12?,14?-tetrol. We isolated all isomers of the tetrol. We also found that the 5,7,12,14-thienylpentacene-5?, 7?,12?,14?-tetrol can undergo rearrangement to afford both 5,5?,7,7?-tetrathienylpentacene-12,14-one and 5,5?,12, 12?-tetrathienylpentacene-7,14-one.

Synthesis, structure, and both cathodic and anodic reversible redox reactions of benzochalcogenophenes containing ferrocene units

2,3-Diferrocenylbenzo[b]thiophene and 1,3-diferrocenylbenzo[c]thiophene have been systematically and selectively synthesized from benzo[b]thiophene and phthaloyl dichloride, respectively. Characterization of the molecules was performed by physical and spectroscopic means and X-ray crystallographic analyses. The cyclic voltammograms of the novel thiophene derivatives containing ferrocene fragments showed a well-defined reversible cathodic step derived from the unusually stable thiophene radical anions and two distinct reversible anodic steps derived from ferrocenium cations separated from each other by a thiophene heterocycle. 1,3-Diferrocenylbenzo[c]selenophene was also synthesized in a similar manner for formation of 1,3-diferrocenylbenzo[c]thiophene by the use of bis(dimethylaluminum) selenide as a selenating reagent.
