One-Pot Synthesis of Tetracyanocyclopropane Derivatives Using Hexamethylenetetramine-Bromine (HMTAB)

Abstract

Herein a direct method for synthesis of tetracyanocyclopropanes by the treatment of carbonyl compounds, malononitrile and hexamethylenetetramine-bromine (HMTAB) is described in the presence of catalytic amount of DABCO in ethanol media at room temperature.
