The reaction of silicon with methyl chloride was carried out in the presence of butadiene. The products consisted of 1,1-dichlorosila-cyclopent-3-ene, 1-methyl-1-chlorosilacyclopent-3-ene and 1-chlorosilacyclopent-3-ene besides methylchlorosilanes. Silacyclopent-3-enes accounted for 25% of the whole products. The high selectivity for silacyclopent-3-enes indicates that surface silylene is the intermediate in the reaction of silicon with methyl chloride.
