Synthesis of a hafnocene disilene complex

J Am Chem Soc. 2005 Jan 12;127(1):70-1. doi: 10.1021/ja0464387.

Abstract

Reaction of the magnesium transmetalation product of a 1,2-dipotassiodisilane with hafnocene dichloride gives a disilene hafnocene complex. X-ray crystallography of the respective trimethylphosphane adduct provides structural proof for this assignment.
