Sonochemical cleavage of 2-(bromomethyl)aziridines by a zinc–copper couple
摘要:
1-Alkyl- and 1-arylmethyl-2-(bromomethyl)aziridines are readily cleaved by the sonochemical zinc-copper couple in aqueous methanol at room temp. to afford allylamines.

1-alkyl-2-(bromomethyl)aziridines were transformed into 1-alkyl-2-(N-alkyl-N-ethylaminomethyl)aziridines upon treatment with 2-3 equiv. of methyllithium in THF or Et(2)O; the peculiarity in this transformation comprises the presence of an N-ethyl group in the end-products as well as the total number of carbon atoms, resulting from a highly unusual reaction course with a novel S(N)2'-type substitution
