Bisacylphosphine oxides of the general formula ##STR1## wherein R.sup.1 stands, for example, for a straight-chain or branched C.sub.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.sub.1 -C.sub.12 alkyl and/or C.sub.1 -C.sub.12 alkoxyl, or an S or N-containing 5-membered or 6-membered heterocyclic ring, and R.sup.2 and R.sup.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.sub.1-4 alkyl and/or C.sub.1-4 alkoxyl, or an S or N-containing 5-membered or 6-membered heterocyclic ring; or R.sup.2 and R.sup.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.sub.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.
一般式为##STR1##的双酰基膦氧化物,其中R1代表直链或支链C1-18烷基基团,环己基、环戊基、苯基、萘基或联苯基基团,被F、Cl、B、I、C1-C12烷基和/或C1-C12烷氧基取代的环戊基、环己基、苯基、萘基或联苯基基团,或含有S或N的5元或6元杂环;R2和R3相同或不同,代表环己基、环戊基、苯基、萘基或联苯基基团,被F、Cl、Br、I、C1-4烷基和/或C1-4烷氧基取代的环戊基、环己基、苯基、萘基或联苯基基团,或含有S或N的5元或6元杂环;或者R2和R3连接形成含有4-10个碳原子的环,并且可以被1-6个C1-4烷基基团取代。这些化合物是通过对应的双酰基膦的氧化制备的。这些化合物适用于含有乙烯基不饱和键的化合物的光聚合引发剂。
