Dibromobenzene, dibromothiophenes, dichloro- and dibromopyridine are highly selectively mono-alkylated and arylated with Grignard or organozinc reagents in the presence of palladium complexes as catalysts.

Photolysis of substituted thiophene-S-oxides in solution results in the formation of either the corresponding thiophene or furan, in addition to uncharacterized materials. No good rationalization is available for the choice of which pathway may predominate, but it is demonstrated that the photolysis of 2,5-bistrimethylsilylthiopene- S-oxide produces O(3P) in the same manner as the well-established

A method of manufacturing an intrinsically conductive polymer crosslinking at least a portion of an intrinsically conductive polymer precursor in the solid state, the swollen state, or combinations comprising at least one of the foregoing states, wherein the swollen state is characterized as being one wherein the intrinsically conductive polymer precursor increases in volume upon exposure to a solvent without completely dissolving in the solvent. In another embodiment, a method of manufacturing a pattern comprises casting a film of an intrinsically conductive polymer precursor on a substrate; and crosslinking at least a portion of the film by oxidation, wherein the crosslinking occurs in the solid state, the swollen state or combinations comprising at least one of the foregoing states.
