Silaethene Me2Si=C(SiMe3)3 (1), unstable at -100 degC with regard to dimerization, forms an adduct Me2Si=C(SiMe3)2NMe3 (3) with trimethyl amine, metastable at 0 degC.It decomposes thermally to give 1 and NMe3 and can, therefore, serve as a source of 1.With 1 as an intermediate, the adduct 3 reacts with butadiene, cyclopentadiene, 2,3-dimethylbutadiene, Ph2C=NSiMe3, t-BuN3, isobutene, or acetone giving either cycloadducts or ene reaction products.Adduct 3 reacts with ROH (R0H, Me, t-Bu, Ph) to yield insertion products, probably by way of a proton adduct of 3, but not via 1.Other donors (D) of which NMe3 is an example form adducts 1D, producing a new class of silicon compounds.As the Lewis basicity of D, relative to 1, decrease (F- >NMe3>NEt3>Br->THF), the resistance to decomposition of the adducts 1D to the dimer of 1 and D also decreases.
