## Abstract An efficient protocol for the __ortho__‐aroylation of 2‐arylbenzothiazoles and 2‐arylbenzoxazoles has been developed using aldehydes as the aroyl source. This Pd‐catalyzed substrate‐directed sp^2^‐hybridized C–H bond functionalization occurs in the presence of the oxidant __tert__‐butyl
## Abstract The syntheses of polyethynyl‐substituted 2,2′‐bithiophenes 2 and related 5,5′‐dicarbaldehyde derivatives 1 are described. The treatment of easily available polybrominated 2,2′‐bithiophenes 3 and 2,2′‐bithiophene‐5,5′‐dicarbaldehydes 4 with phenyl or (trimethylsilyl)acetylene in the pres
