Cycloaddition reactions of N-thioacyl dithioimidocarbonates

Abstract

N-Thioacyl dithioimidocarbonates undergo 1,2- and 1,4-cycloaddition reactions with active olefins, diphenylketen, and diphenyldiazomethane; the products obtained with the latter two reagents differ from those obtained in the reactions with a related conjugated system, thioacylketen thioacetal.
