Zusammenfassung:
An efficient procedure for the preparation of methylenecyclopropane (3), a valuable starting material in organic synthesis, has been developed from methallyl chloride (1) and alkali metal [bis(trimethylsilyl)lamide [M(BTMSA) (M = Na, K), 2b.c]. The advantages of this new method are the higher yield of methylenecyclopropane up to 79% and a homogenous reaction mixture, i.e. both substrates are soluble in organic solvents such as toluene and dibutyl ether.
