ABSTRACT:
A method is provided for making certain aryl onium salts of Group VIa elements useful as photoinitiators for polymerizing various organic materials. Reaction is effected between a compound of a Group VIa element, for example, an aryl or alkyl sulfide or a thiophenol or mercaptan and an aromatic iodonium salt in the presence of a copper compound catalyst or a copper compound-tertiary amine cocatalyst.
