Abstract

The silylene Si[(NCH₂Bu^t)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.
