摘要: Abstract A number of gem-bromochlorocyclopropanes has been prepared by the reaction PhHgCClBr2-derived bromochlorocarbene with olefins (cyclohexene, cyclooctene, 1-heptene, tetramethylethylene, cis- and trans-2-butene, styrene, acrylonitrile, vinyl acetate, allyltrimethylsilane, vinyltrimethylsilane, trans-1,2-dichloroethylene). Reaction phenyl(dibromochloromethyl)mercury 2,5-dihydrofuran gave an equimolar amount expected CC addition product CH insertion product, 2-(bromochloromethyl)-2,5-dihydrofuran. Similar was observed tetrahydrofuran. With cumene CClBr occurred exclusively into benzylic position.
