C–H Activation of Methyl Arenes in the MnO2-Mediated Aroylation of N-Chlorosulfoximines
摘要:
An investigation into the reactivity profile of N-halogenated sulfoximines has led to the development of a new method for the synthesis of N-aroylated sulfoximines. This protocol involves the manganese oxide promoted C-H activation of methyl arenes to form an aroyl intermediate which then reacts readily with N-chlorosulfoximines to form a series of valuable aroyl sulfoximine derivatives in high yields.

A visible-light-promoted, PIDA/I2-mediated acylation of NH-sulfoximines with methylarenes as an acyl source has been achieved. This transition metal and photosensitizer-free approach provides easy access to N-acylsulfoximines via oxidative coupling of sulfoximines with easily available methylarenes without using any peroxide source. Mechanistic investigations suggest the intermediacy of radicals and
