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.
