Process for preparing silicon-containing vinyl ethers and vinyl thioethers of the general formula I ##STR1## where the variables have the following meanings: X is oxygen or sulfur, R.sup.1 is C.sub.1 -C.sub.20 -alkylene, C.sub.3 -C.sub.12 -cycloalkylene or C.sub.6 -C.sub.10 -arylene, R.sup.2, R.sup.3 and R.sup.4 are hydrogen, C.sub.1 -C.sub.20 -alkyl, C.sub.3 -C.sub.12 -cycloalkyl, C.sub.1 -C.sub.12 -alkoxy, phenoxy, heteroaryl or together with R.sup.1 form a C.sub.3 -C.sub.12 -cycle, by reaction of silicon-containing alcohols or thiols of the general formula II ##STR2## where the variables have the meaning indicated above, with acetylene, by carrying out the reaction in phenyl methyl sulfoxide, dimethyl sulfoxide, sulfolane or hexamethylphosphoramide in the presence of an alkali metal hydroxide.
制备含硅基的通式I的乙烯基醚和乙硫基醚的过程,其中变量的含义如下:X为氧或硫,R1为C1-C20-烷基,C3-C12-环烷基或C6-C10-芳基,R2、R3和R4为氢,C1-C20-烷基,C3-C12-环烷基,C1-C12-烷氧基,苯氧基,杂环芳基或与R1一起形成C3-C12-环。通过将通式II的含硅醇或硫醇(其中变量的含义如上所述)与乙炔反应,在苯甲基亚磺酰甲烷,二甲基亚磺酰甲烷,磺缩醛或六甲基膦酰胺存在碱性金属氢氧化物的情况下进行反应。
