Silyl enol ethers were produced by the carbonyl olefination of silyl esters with titanium carbene complexes generated by the desulfurizative titanation of thioacetals. The regioselective preparation of silyl dienol and trienol ethers has been achieved by using unsaturated silyl esters and thioacetals.
甲硅烷基烯醇醚是通过将甲硅烷基酯的羰基烯化与硫代乙缩醛的脱硫钛化反应生成的钛碳烯配合物而制得的。甲硅烷基二烯醇和三烯醇醚的区域选择性制备已经通过使用不饱和甲硅烷基酯和硫代缩醛实现。
