Abstract
The silylene Si[(NCH2But)2C6H4-1 ,2] 1 inserts into the Li–Si bond of Li[Si(SiMe3)3](thf)3 to afford the new silyllithium compound Li[(1)Si(SiMe3)3](thf)2 2, whereas 1 with K[N(SiMe3)2] yields the amidopotassium compound K[N(SiMe3){(1)(SiMe3)}](thf)x [x = 0 (3a) or 3 (3b)]; the X-ray structures of the crystalline mononuclear complex 2 and the polymeric aggregate 3a are reported, and NMR spectra show that in solution 2 is in equilibrium with its factors.Keywords
