(Halomethyl)zinc cyclopropanation reagents have been investigated by solution NMR and X-ray crystallographic methods. Treatment of glycol-ether complexes of diethylzinc with chloroiodomethane or diiodomethane quantitatively produced glycol-ether complexes of bi(chloromethyl)zinc and bis(iodomethyl)zinc, respectively. Similarly, treatment of acetone solutions of diethylzinc with either dihalomethane
