Abstract

The thermally stable silylene Si[(NCH2But)2C6H4-1,2] 1 undergoes oxidative addition reactions with the alkali metal silylamides MN(SiMe3)2 (M = Li, Na or K) to afford the new alkali metal amides MN(SiMe3)[(1)SiMe3] [M = Li (2), Na (3) or K (4)]. Reaction of two equivalents of 1 with LiN(R)(SiMe3) leads in a two-step process to the compound LiN[(1)R][(1)SiMe3] [R = SiMe2Ph (5) or SiMe3 (6)]. Alternatively, 1 reacts with 3 to afford NaN[(1)SiMe3]2 (7). The structures of 2–5 and 7 are presented and the formation of 2–7 is discussed.
