  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.

  Iodomethylboron compounds, either the trifluoroborate or a boronic ester, cyclopropanate electron-rich olefins and unprotected allylic alcohols with Pd catalysts according to a novel, designed catalytic cycle. Proposed intermediates in a "diverted Heck" mechanism are observed by means of spectroscopic studies and by isolation and X-ray crystallographic characterization, which together with reaction kinetics point to a separation of rate-determining and product-determining steps, and a mechanism-based optimization of the yield, selectivity, and scope of the catalytic electrophilic cyclopropanation. The reaction with crystalline, air-stable, nonhygroscopic, and nontoxic reagents provides an alternative to Simmons Smith-type reactions, as well as cyclopropanation procedures that require the use of diazomethane.
