Basic Resin Mediated Efficient One-Pot Synthesis of Carbazates from the Corresponding Alkyl Halides

A quick and efficient, one-pot synthesis of carbazates was accomplished in high yields by the reaction of various primary, secondary, and tertiary alkyl halides with a variety of substituted hydrazines using Amberlite IRA 400 basic resin/CO2 system. The reaction conditions were mild with simpler work-up procedures than the previously reported methods.
