Abstract

The three-membered silacyclic ring compounds LSi[N2(Ph)2]tBu (1), LSi[HCN(Ph)2]tBu (2) and LSi[C2(Ph)2]tBu (3) were obtained by the treatment of base stabilized monoalkylsilylenes LSitBu (L = PhC(NtBu)2) with PhN[double bond, length as m-dash]NPh, PhN[double bond, length as m-dash]CHPh and PhC[triple bond, length as m-dash]CPh. The reaction of PhN[double bond, length as m-dash]NPh and PhC[triple bond, length as m-dash]CPh with LSitBu shows a different reactivity pattern with base stabilized monochlorosilylene LSiCl. The arrangement of the three-membered ring (SiNN) in 1 is the first structurally isolated example of a siladiaziridine compound.
