Abstract

The base-free reaction of LiSiMe3 with CpBeCl in pentane affords the air-sensitive, volatile solid CpBe (SiMe3); this compound provides the first example of a direct bond between beryllium and a non-carbenoid group 14 element. Prolonged heating (~ 200° C) of the title compound generates equimolar amounts of CpBe (SiMe2SiMe3) and CpBeMe; dimethylsilyene, Me2Si:, is a likely thermolysis intermediate.
