Bis(trimethylsiloxy)-1,3-dienes 5a - n are obtained by reaction of 1,3-dicarbonyl compounds 1 with trimethylsilyl trifluoromethanesulfonate (2) in the presence of triethylamine (3).The silyl enol ether 8 is silylated by 2/3 to yield 1,3-bis(trimethylsiloxy)-1,3-butadiene (5o).Depending on the conditions, alkyl 3-oxobutanoates 12 react with 2/3 to give the γ-silylated alkyl 3-trimethylsiloxy-2-butenoates 15 or 16.
