Unprecedented insertion reaction of a silylene into a B-B bond and generation of a novel borylsilyl anion by boron-metal exchange reaction of the resultant diborylsilane

A kinetically stabilized diarylsilylene, Tbt(Mes)Si: (1, Tbt = 2,4,6-tris[bis(trimethylsilyl)methyl]phenyl, Mes = mesityl), thermally generated from overcrowded disilene Tbt(Mes)Si=Si(Mes)Tbt (2) or stable silylene-isocyanide complex (3a), was found to in

Synthesis of alkali metal salts of borylsilyl anions utilizing highly crowded silylboranes and their properties

The lithium salt of a borylsilyl anion, [Tbt(Mes)SiBpin]-Li + (11: Tbt = 2,4,6-tris[bis(trimethylsilyl)-methyl]phenyl, Mes = mesityl, pin = pinacolato), was synthesized by the boron-metal exchange reaction of a diborylsilane, Tbt(Mes)Si(Bpin)2 (8), which was synthesized by the insertion of a highly crowded diarylsilylene, Tbt(Mes)Si: (1), into the B-B bond of a diborane(4) compound, B2pin2. Although a salt of the borylsilyl anion 11 could not be isolated due to its thermal instability, the investigation of the reactivity of the anion revealed that 11 is a possible precursor for Si-functionalized silylboranes as well as Si,Si-difunctionalized silanes. Furthermore, the borylsilyl anion [Tbt(Mes)SiBScat]- (27: Scat = dithiocatecholato), which was synthesized by a procedure similar to that used for 11, showed a reactivity different from that of 11. Theoretical calculations for the borylsilyl anions revealed that the anion 27 has a boratasilene character; namely, the Si-B bond has a double-bond character due to the donation of an electron pair of the negatively charged silicon atom into the vacant p-orbital of the adjacent boron atom.
