Efficient method for the synthesis of monohalocyclopropanes by reduction of gem-dihalocyclopropanes with i-Bu2AlH in the presence of Ti and Zr complexes
摘要:
We have investigated the reductive dehalogenation reaction of alkyl and aryl substituted gemdihalocyclopropanes with diisobutyl aluminum hydride in the presence of catalytic amounts of titanium and zirconium complexes. As a result we propose a general method for the synthesis of substituted monohalocyclopropanes and cyclopropanes of various structures. We have also studied the stereochemistry of the reduction.

A versatile stereoselective method is presented for the synthesis of cis-monochlorocyclopropanes by the reduction of dehalogenated alkyl- and aryl-gem-dichlorocyclopropanes in the presence of catalytic quantities of titanium and zirconium complexes.
