Abstract: The facile synthesis of the first stable selenosilanoic acid–base adduct LSi([double bond, length as m-dash]Se)OH(dmap) 3 (L = CH[C(Me)NAr]2, Ar = 2,6-iPr2C6H3, dmap = 4-dimethylaminopyridine), the heavier analogue of the thiosilanoic acid adduct LSi([double bond, length as m-dash]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([double bond, length as m-dash]E)OCu]2 (4: E = S; 5: E = Se) with unprecedented intermolecular Si[double bond, length as m-dash]E → Cu–O–Si coordination modes. The latter are efficient pre-catalysts for the Cu(I)-mediated aziridination of styrene with PhI[double bond, length as m-dash]N(Ts) (Ts = tosyl).
