Procedure

A solution of 2-(diphenylphosphino)ethyltrimethoxysilane (DPETMS) in isopropanol comprising 12% DPETMS and 88% isopropanol and 2-4 drops titanium acetylacetonate dialkoxide in alcohol was prepared. The DPETMS was synthesized by combining diphenylphosphine and vinyltrimethoxysilane in a borosilicate flask and then exposing to sunlight for 100 hours, or by using t-butylperoxide or azodiisobutryronitrile as a catalyst. Excess volatile material was removed in vacuo at 1-2 mmHg pressure and the remaining material tested.
