Reaction of oxygen-containing monomers with triethylsilane in the presence of iron, manganese, and rhenium carbonyls

Abstract

A study was carried out on the reaction of triethylsilane (TES) with acrolein, the diethyl acetal of acrolein, and allyl alcohol in the presence of Fe(CO)5 Mn2 (CO) 10,and Re 2 (CO) 10.Acrolein reacts with TES in the presence of Fe(CO)5 to give the 1,4-addition product in high yield. The reaction of the diethyl acetal of acrolein largely features cleavage of the C- O bond and formation of Et3SiOEt.Allyl alcohol reacts with TES in the presence of Fe(CO)5, Mn2 (CO) 10,and Re2 (CO) 10 to give the dehydrocondensation product, namely, triethylallyloxysilane, which undergoes hydrogenation and hydroxylation to give triethylpropyloxysilane and γ-(triethylsilyloxy)propyltriethylsilane, respectively. The yields of these products depend on the metal carbonyl used.
