An access to base-stabilized three-membered silicon heterocycles?
Dalton Transactions Pub Date: 2012-06-28 DOI: 10.1039/C2DT31326J
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]](https://www.rsc.org/images/entities/char_e001.gif)
NPh, PhNCHPh and PhC![[triple bond, length as m-dash]](https://www.rsc.org/images/entities/char_e002.gif)
CPh. The reaction of PhNNPh and PhCCPh 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.
