Abstract

3-Methyl-3-trimethylsilylcyclopropene (1) was prepared by reacting (Z)-3-trimethylsilyl-2-butenyl chloride (5) with sodium amide. This compound (1) was converted to 1,2-dibenzoyl-3-methyl-3-trimethylsilylcyclopropene (2), a rare example of an isolable cyclopropene with two electron withdrawing groups at the vinyl position, and the thermal isomerization of 2 was probed.
