Dimethylation
and Hydrodechlorination of gem-Dichlorocyclopropanes with Grignard Reagents Promoted by Fe(III) or Co(II) Catalyst.
-The reductive dechlorination of gemdichlorocyclopropanes is investigated. The best results are achieved with CoCl 2 (dppe) as a catalyst using Grignard compounds as reductive reagent. A mixture of syn-and antimonochlorides is obtained. Fe, Co, and Ni-catalysts are screened for dimethylation of gem-dichlorocyclopropanes. Fe(dbm) 3 shows the highest reactivity yielding gem-dimethylcyclopropanes. Some of the products constitute important moieties for natural products. -(NISHII, Y.; WAKA-
