Rhodium(III)-Catalyzed Ortho Halogenations of N-Acylsulfoximines and Synthetic Applications toward Functionalized Sulfoximine Derivatives.

Rhodium(III)-catalyzed ortho brominations and iodinations of N-acylsulfoximines by C-H bond activations have been developed. Subsequent product functionalizations involving cross-coupling reactions provide alkynylated sulfoximine derivatives and benzothiazines with wide potential for further synthetic applications.
