Abstract

Dichlorobis[bis(trimethylsilylamido)]hafnium(IV) reacts with (R2P[double bond, length half m-dash]NSiMe3)2CH2 (R = Cy, Ph) cleaving the C–H bonds of the P–C–P backbone methylene group and eliminating 2 mol of hexamethyldisilazane to yield the hafnium methandiide (carbene) complexes 3 and 4, thus completing the triad of group 4 metal complexes containing the M[double bond, length half m-dash]C moiety.
