Abstract

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, PA1 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 PA1 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 phosphi…
