Direct transformation of silyl enol ethers into functionalized allenes
The first elimination reactions of silyl enol ethers to lithiated allenes are reported. These reactions allow a direct transformation of readily available silyl enol ethers into functionalized allenes. The action of three to four equivalents of lithium di
BIS(TRMETHYLSILYL)-1,3 ALCYNES-1 : PREPARATION A PARTIR DE SILANES PROPARGYLIQUES ET APPLICATION A LA SYNTHESE DE SILANES ALLENIQUES α-FONCTIONNELS
1,3-bis(trimethylsilyl)-1-alkynes may be obtained from trimethylsilylpropargylsilanes by metallation with n-butyllithium following by reaction with trimethylsilylchloride ; these silanes easily react with acetals, in presence of titanium tetrachloride, to produce α-functional allenyltrimethylsilanes.
