1,1-Dichloro-2-(chloromethyl)cyclopropane (1) reacts with phenols 2a-l, alcohols 2m,n or thiophenol (2o) in different base/solvent systems, to form either 2-(aryloxymethyl)-1,1-dichlorocyclopropanes 3 and/or 1,1-bis(aryloxy)-2-methylenecyclopropanes 4. Reaction of 1 with piperidine (2p) and sodium cyanide (2q) affords 1,1-dichloro-2-(piperidinomethyl)cyclopropane (3p) and 1, 1-dichloro-2-(cyanomethyl)cyclopropane (3q), respectively. The kind of the products formed depends on the reaction conditions and the structure of the heteronucleophile.
