Abstract: A cobalt-catalyzed decarboxylative cross-coupling reaction of (hetero)aryl carboxylic acids with benzothiazoles or benzoxazoles is reported. This represents a first example of metal-catalyzed decarboxylative C-H heteroarylation of benzo-fused heterocycles. The transformation provides a convenient route, with… read more here.

Abstract: Dioxyheterocycles, particularly 3,4-ethylenedioxythiophene (EDOT), have proven to be useful building blocks for conjugated materials targeting various applications. The 3,4-phenylenedioxythiophene (PheDOT) unit is similar to the EDOT unit in terms of planarity and steric interactions, but… read more here.

Abstract: Herein we report on the first successful coupling of the dithienophosphole (S2PO) functional building block with three types of heteroaryl end caps using direct (hetero)arylation C–H bond functionalization methods. As a model reaction, S2PO was… read more here.
