Factors affecting the regioselectivity of the catalytic reaction of methyl diatoacetate with 1-trimethylsilylalkene-1-ynes have been revealed. Conditions for selective cyclopropanation of the double bond in 1-trimethylsilylbut-3-ene-1-yne and 1-trimethylsilyl-3-methylbut-3-ene-1-yne in the presence of Rh2(OAc)4 have been found.
