Abstract
Compounds according to general formula (I) in which M is Ge or Sn, RAr is R, R, R, R, R, independently of one another in each case, are —H, —F, —Cl, —OR, —SR, —N(R), —CF, —CN, —NO, —COOR, —CONHR, a branched, cyclic or preferably linear Calkyl, Calkenyl, Calkyloxy or a Calkenoxy radical, which can be interrupted one or more times by O, S or —NR— and substituted by one or more polymerizable groups and/or radicals R, Ris H, a branched, cyclic or preferably linear Calkyl or Calkenyl radical, Ris a chemical bond, an n-valent aromatic radical or a branched, cyclic or preferably linear Calkylene radical, which can be interrupted one or more times by O, S or —NR— and substituted by one or more polymerizable groups, ═O and/or radicals R, n is 2 or 3 and m is 0 or 1. The compounds are particularly suitable as photoinitiators for radical polymerization and in particular for the production of dental materials.
