Abstract

The results in Table I1 are reproducible only when oxygen is rigorously excluded from the reaction mixture. These reactions may be carried out with less than 1 mol equiv of activated Fe (0); 8 we have obtained comparable results using as little as 0.5 mol equiv of Fe (0) 8 in several of the cases listed. The mechanism of this unusual reaction remains obscure. Unlike reactions with Fe (0) 8 alone, the reaction employing excess Grignard reagent is very ...
