Nickel-Catalyzed Reductive Csp2-Csp3Cross Coupling Using Phosphonium Salts

A nickel-catalyzed reductive cross coupling with phosphonium salts and allylic C(sp3)-O bond electrophiles, which granted direct construction of the C(sp2)-C(sp3) bond, is successfully developed. The protocol features broad substrate scope, high-functional-group tolerance, and heterocycle compatibility. Notably, the much more challenging reductive cross coupling with heterocyclic thiazolylphosphonium salts has also been accomplished for the first time.

A simple synthesis of new carbinols from bis(2-benzothiazolyl) ketone

The addition reactions of Grignard reagents to the keto group of bis(2-benzothiazolyl) ketone afford bis(2-benzothiazolyl)alkyl, allyl and alkynyl carbinols in high yields without other side reactions, such as carbonyl group reduction and addition of the

REACTION OF 2-HETEROSUBSTITUTED BENZOTHIAZOLES WITH ALLYLIC GRIGNARD REAGENTS

The title benzothiazoles 1 react with allylic Grignard reagents affording 2-allylbenzothiazoles 5, 2,2-diallylbenzothiazolines 6 and N-triallylmethyl-o-aminobenzenethiols as disulphides 7 depending upon the experimental conditions.The reaction is considerably influenced by the solvent used and the nature of the allylic Grignard.A possible mechanism for the formation of compounds 5, 6 and 7 is reported.
