Acylphosphine oxide compounds of the general formula ##STR1## where R.sup.1 is alkyl, cyclohexyl, cyclopentyl, aryl which is unsubstituted or substituted by halogen, alkyl or alkoxy, or an S-containing or N-containing five-membered or six-membered heterocyclic radical, R.sup.2 has one of the meanings of R.sup.1 (but R.sup.1 and R.sup.2 may be identical or different), or is alkoxy, aryloxy or aralkoxy, or R.sup.1 and R.sup.2 together from a ring, and R.sup.3 is straight-chain or branched alkyl of 2 to 18 carbon atoms, a cycloaliphatic radical of 3 to 12 carbon atoms, phenyl or naphthyl which are alkyl-, alkoxy- or thioalkoxy-substituted, or an S-containing or N-containing five-membered or six-membered heterocyclic radical, and may contain additional functional groups, or is the group ##STR2## where R.sup.1 and R.sup.2 have the above meanings and X is phenyl or an aliphatic or cycloaliphatic divalent radical of 2 to 6 carbon atoms, and one or more of the radicals R.sup.1 to R.sup.3 may be olefinically unsaturated, a process for the preparation of these acylphosphine oxide compounds from acid halides of the general formula ##STR3## where X is chlorine or bromine, and a phosphine of the general formula ##STR4## and the use of the acylphosphine oxides as photoinitiators in photopolymerizable compositions.
一般式为##STR1##的酰基膦氧化物化合物,其中R.sup.1是烷基,环己基,环戊基,苯基,未取代或取代卤素,烷基或烷氧基,或含S或N的五元或六元杂环基团,R.sup.2具有R.sup.1的其中一种含义(但R.sup.1和R.sup.2可以相同或不同),或者是烷氧基,芳氧基或芳烷氧基,或R.sup.1和R.sup.2一起形成一个环,R.sup.3是直链或支链烷基,碳数为2到18,3到12个碳原子的环状脂肪基,被烷基,烷氧基或硫代烷氧基取代的苯基或萘基,或含S或N的五元或六元杂环基团,并且可以含有其他官能团,或是##STR2##的基团,其中R.sup.1和R.sup.2具有上述含义,X是苯基或2到6个碳原子的脂肪或环状二价基团,R.sup.1到R.sup.3中的一个或多个基团可以具有烯丙基不饱和性,制备这些酰基膦氧化物化合物的方法包括使用一般式为##STR3##的酸卤化物,其中X是氯或溴,和一般式为##STR4##的膦化合物,以及将酰基膦氧化物用作光聚合组合物的光引发剂。
