The catalyzed reaction of methyl-, propyl-, and cyclopropyltrimethylsilylacetylenes with diazomethane in the presence of CuCl leads to the corresponding cyclopropenes and bicyclobutanes with overall yields of up to 70%, and also to the products of incorporation of a methylene group into the C3-H bond of the cyclopropenes formed (2-9%). Partial catalyzed isomerization of the 1-trimethylsilyl-2-cyclopropylcyclopropene formed from trimethylsilylcyclopropylacetylene, into 1-trimethylsilyl-1-cyclopropylallene (yield approximately 50%) was discovered to proceed under the reaction conditions.
