Abstract

Abstract Bisacylphosphine oxides of the general formula ##STR1## wherein R 1 stands, for example, for a straight-chain or branched C 1-18 alkyl radical, a cyclohexyl, cyclopentyl, phenyl, naphthyl, or biphenylyl radical, a cyclopentyl, cyclohexyl, phenyl, naphthyl, or biphenylyl radical substituted by F, Cl, B, I, C 1 -C 12 alkyl and/or C 1 -C 12 alkoxyl, or an S or N-containing 5-membered or 6-membered heterocyclic ring, and R 2 and R 3 , which are the same or different, stand for a cyclohexyl, cyclopentyl, phenyl, naphthyl, or biphenylyl radical, a cyclopentyl, cyclohexyl, phenyl, naphthyl, or biphenylyl radical substituted by F, Cl, Br, I, C 1-4 alkyl and/or C 1-4 alkoxyl, or an S or N-containing 5-membered or 6-membered heterocyclic ring; or R 2 and R 3 are joined to form a ring which contains from 4 to 10 carbon atoms and which may be substituted by 1 to 6 C 1-4 alkyl radicals. The compounds are prepared by oxidation of the corresponding bisacylphosphines. The compounds are suitable for use as initiators for the photopolymerization of compounds containing ethylenically unsaturated bonds.
