Abstract: Treatment of the amidinato amidosilylene [L{(Me3Si)2N}Si:] [1, L = PhC(NtBu)2] with a slight excess of borane-tetrahydrofuran complex [BH3·THF] in toluene at room temperature afforded the silylene-borane adduct [L{(Me3Si)2N}Si:→BH3] (2). A triflate substituent was introduced on… read more here.

Abstract: A base-stabilized C-phosphonio-Si-amino-silyne 3 was synthesized, using an original method, through a coupling reaction between two Lewis-base-stabilized low-valent species: a silyliumylidene ion 1 and a P,S-bis-ylide 2 [C(0)-complex]. This new isolable cationic silyne 3 displays… read more here.
