To form the radical by oxidation, the substance is shaken with a ten-fold excess of active PbO;! in benzene for 10 min. On rapid removal of the solvent, the reddish-brown solution affords an impure, reddish-brown paramagnetic product.

The treatment of 4-chlorobutyronitrile, 3-chloropropyl phenyl sulfone, and other related compounds with a base afforded gamma-halocarbanions that undergo fast intramolecular substitution of the halogen to produce substituted cyclopropanes. We found that these short-lived carbanionic intermediates ca
