Abstract

Synthesis and Properties of Halogen-Containing Allyl Series Epoxy-Compounds. -Reaction of allylic alcohol (I) with epichlorohydrin provides access to epoxide (III) containing a 2-haloallyl substituent. On reaction with KOH, dehydrohalogenation proceeds at the allylic residue to furnish an epoxide containing an tethered ethynyl residue (VII), while the reactions with amine (IV) and thiourea take place at the epoxide ring. A second synthetic access to halogen-substituted allylepoxides [e.g. (X)] is presented, involving the reaction of α,β-dihaloaldehyde (VIII) with allylmagnesium bromide. -(VELIYEV, M.
