with indiummetal, and their reactions with carbonyl compounds and electron-deficientalkenes were examined. The reactions of simple 1,1-diiodoalkanes with indiummetal gave no defined products but benzal iodide gave stilbene in a moderate yield. α-Halo organoindium reagents drived from α,α-dibromo carbonyl compounds gave oxiranes and cyclopropanes upon the reactions with aldehydes and alkenes, respectively
Aryl(chloro)methyl 4-tolyl sulfoxides were synthesized from arylmethyl 4-tolyl sulfoxides in moderate-to-good yields by sequential treatment with lithium diisopropylamide and tosyl chloride at low temperatures. Treatment of the lithium α-sulfinyl carbanion of the aryl(chloro)methyl 4-tolyl sulfoxides with aldehydes or ketones resulted in the formation of adducts in good-to-high yields. Treatment of
