Treatment of trimethylsilyl esters with a reagent for alkylidenation of carbonyl groups derived from 1,1-dibromoalkane, zinc, TiCl4, and TMEDA in THF gives Z-trimethylsilyl enol ethers in a regio- and stereoselective manner.

The method of synthesis of the hitherto unknown class of organosilicon compounds, phenyl(acyloxy)fluorosilanes C6H5Si(OCOR) (n) F3-n (n = 1, 2) and phenyl(acyloxy)fluorochlorosilanes C6H5Si(OCOR) FCl in up to 91% yield has been developed based on the reaction of phenyl(fluoro)chlorosilanes C6H5SiCl (n) F3-n (n = 1, 2) with trimethylsilyl esters of carboxylic acids Me3SiOC(O)R [R = H, CH3, CF3, CCl3, ClCH2, BrCH2, CH2=CHCH3, CH2=CHPh, CH(CH3)=CH2, Ph].
