Abstract
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)]amide [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.
Key words
methylenecyclopropane - methallyl chloride - elimination
