Reactions of organolanthanide compounds RLnI (Ln = Yb, Eu, Sm) with organic derivatives of silicon, tin, lead, and antimony

Reactions of compounds RLnI (R = Alk, Ar; tn = Yb, Eu, Sm) with hexaalkyl(a ryl)-distannanes, trimethylsilyltriphenyltin, and lead and antimony acetate s were studied. The reactions with Sn-Sn and Si-Sn organic derivatives resu lt in cleavage of Sn-Sn amd Sn-Si bonds with fort-nation of tetrasubstitute d stannanes and reactive organometallic derivatives with an Sn-Ln or Si-Ln bond. The reactions of RYbI with lead and antimony acetates and with tetrae thoxysilane cause cleavage of the Pb-O, Sb-O, or Si-O bond with formation o f tetrasubstituted derivatives of lead and silicon or trisubstituted antimo ny derivatives.
