III-VI of the periodic table; R<9> = H, 1-10C alkyl, opt. 1-10C alkyl substd. 5-7 membered cycloalkyl, 6-15C aryl(alkyl) in which two neighbouring gps. may opt. form 4-15C cyclic gps., Si(R<13>)3 or a gp. of formula: R<13> = 1-10C alkyl, 6-15C aryl or 3-10C cycloalkyl; Q<2> = N, P, As, Sb, or Bi; R<14>, R<15> = 1-10C alkyl, 3-15C cycloalkyl, 6-15C aryl, 1-10C alkyl - 6-20 C aryl, 6-20 C aryl - 1-10C alkyl, 1-10C fluoroalkyl, 6-20 C fluoroaryl or R<14> and R<15> may form a 2-15C heterocyclic gp. contg. 1-8 heteroatoms from main gps. III-VI of the periodic table; Y = gp. of formula; Z = silicon, germanium, tin or carbon; and R<16> - R<19> = H, 1-10C alkyl, 3-10C cycloalkyl or 6-15C aryl, with two neighbouring gps. opt. forming a 4-15C cyclic gps.
