Abstract

N-Boc-N-alkenylhydrazines, an almost unknown type of compounds, have been prepared with high to moderate yields via palladium-catalyzed cross-coupling between alkenyl halides and tert-butyl carbazate. The present methodology represents the first general way to access this highly functionalized and unusual type of hydrazines. [reaction: see text].
