摘要：
A novel process for the preparation of compounds of formula I ##STR1## by aminolysis of a p-halophenyl alkyl ketone of formula II ##STR2## with a cyclic amine of formula III ##STR3## in water at a temperature of at least 130.degree. C., in which formulae X is a halogen atom and R.sub.1, R.sub.2 and R.sub.3 are as claimed in claim 1, as well as the novel compounds of formula I and their use for the preparation of photoinitiators for the photopolymerisation of ethylenically unsaturated compounds.
