Palladium-catalyzed direct alkynylation of thiophenes with halosilylacetylenes

Silylethynylthiophenes were obtained from palladium-catalyzed alkynylation of various thiophenes with 1-halo-2-silylacetylenes. The α-position of thiophenes was alkynylated with high regioselectivity. The terminal silyl groups of products could be replaced by several functional groups.

Photochemical Synthesis of Bithienyl Derivatives

The application of a photochemical arylation of thienyl derivatives to the synthesis of bithienyl compounds is reported.The syntheses of 5-phenyl-2-propynylthiophene and 5-but-3-en-1-ynyl-2,2'-bithienyl are described using as starting materials a phenylthienyl and a bithienyl derivative obtained by this method.Furhtermore, the photochemical synthesis of halogenobithienyl ketones via the photochemical coupling of a halogenothiophene and 2-acetyl-5-iodothiophene is describred.This methodology furnishes a new approach to the synthesis of natural bithienyls.All the synthesized compounds are singlet oxygen photosensitizers, and are, therefore, potentially bioactive compounds.
