Original Paper


The ultimate goal in this paper has been developed for the synthesis of structurally various bromomethyl cyclopropane via an α-bromoketone and/or aldehydes with ethyl cyanoacetate or malononitrile and cyanogen bromide (BrCN) in the presence of Et3N to give products in excellent yields within about 3 s. All structures were characterized by IR, 1H-NMR, 13C-NMR, and Mass spectroscopy techniques. The reaction mechanism was discussed.
