P. Berno et S. Gambarotta, INSERTION VERSUS ELIMINATION IN THE REACTION OF BU(T)NC WITH A AZASILAVANADACYCLOBUTANE RING SUPPORTED BY HEXAMETHYLSILAZANATE LIGAND, Journal of the Chemical Society, Chemical Communications, (20), 1994, pp. 2419-2421
Reaction of the azasilavanadacyclobutane ring of the monomeric [V{(Me(
3)Si)(2)N}{CH(2)SiMe(2)N(SiMe(3))}(py)] with isonitrile gave insertion
and ring expansion, while the same reaction carried out with the meta
llacycle of the meric[V{(Me(3)Si)(2)N}{CH(2)SiMe(2)N{SiMe(3))}](2) for
med an ionic and tetravalent [V{(Me(3)Si)(2)N}(3)]CN complex.
