There is disclosed a method of preparing cyclic silyl enol ethers (1-oxa-2-sila-5-cyclohexenes), comprising reacting a silacyclobutane with an acid halide in the presence of a palladium catalyst and an organic base. There is also disclosed novel cyclic silyl enol ethers obtained by the above method. The above cyclic silyl enol ethers belong to a new class of silyl enol ethers which are useful in the production of medicines and agricultural chemicals, and they can be used as intermediates of fine chemicals or as various reagents for fine synthesis.
本发明公开了一种制备环状硅基烯醇醚(1-氧杂-2-硅-5-环己烯)的方法,包括在钯催化剂和有机碱的存在下,将硅环丁烷与酸卤反应。本发明还公开了通过上述方法得到的新型环状硅基烯醇醚。上述环状硅基烯醇醚属于一种新型硅基烯醇醚类,可用于药物和农业化学品的生产,并可用作精细化学品的中间体或各种精细合成的试剂。
