Abstract: | The three-membered silacyclic ring compounds LSiN(2)(Ph)(2)]tBu (1), LSiHCN(Ph)(2)]tBu (2) and LSiC(2)(Ph)(2)]tBu (3) were obtained by the treatment of base stabilized monoalkylsilylenes LSitBu (L = PhC(NtBu)(2)) with PhN=NPh, PhN=CHPh and PhC≡CPh. The reaction of PhN=NPh and PhC≡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. |
