From elusive thio- and selenosilanoic acids to copper(i) complexes with intermolecular Si
E → Cu–O–Si coordination modes (E = S, Se)†
Abstract
The facile synthesis of the first stable Se)OH(dmap) 3 (L = CH[C(Me)NAr]2, Ar = 2,6-iPr2C6H3, dmap =
S)OH(dmap) 1, is reported. Both adducts 1 and 3 react readily with MesCu (Mes = 2,4,6-trimethylphenyl) to form the novel dimeric Cu(I) complexes [LSi(
E)OCu]2 (4: E = S; 5: E = Se) with unprecedented intermolecular Si
E → Cu–O–Si coordination modes. The latter are efficient pre-
