Efficient synthesis of ${\alpha}$-chloroenones bearing ${\beta}$-carbonates or ${\beta}$-carbamates was achieved by rhodium(II)-catalyzed reaction of cyclic diazodicarbonyl compounds with a variety of chloroformates or carbamyl chlorides in good yields. These reactions provided a useful and rapid route to ${\beta}$-substituted ${\alpha}$-haloenones.
