Insertion versus elimination in the reaction of ButNC with a azasilavanadacyclobutane ring supported by hexamethylsilazanate ligand
Abstract
Reaction of the azasilavanadacyclobutane ring of the monomeric [V{(Me3Si)2N}{CH2SiMe2N(SiMe3)}(py)] with isonitrile gave insertion and ring expansion, while the same reaction carried out with the metallacycle of the dimeric [V{(Me3Si)2N}{CH2SiMe2N(SiMe3)}]2 formed an ionic and tetravalent [V{(Me3Si)2N}3]CN complex.
