Abstract
Abstract An overcrowded 2,2-dihydrosilene bearing 2,4,6-tris[bis(trimethylsilyl)methyl]phenyl (Tbt) and 2,6-diisopropylphenyl (Dip) groups was synthesized as a stable compound both in the solid state and in solution for a long period of time. The newly generated 2,2-dihydrosilene was obtained by exhaustive reduction of the corresponding dibromosilane, Tbt(Dip)SiBr2, with an excess amount of lithium naphthalenide at −78 °C followed by addition of CH2Cl2. The formation of 1 was confirmed by multinuclear NMR studies and extensive theoretical calculations.
