Iron-catalyzed hetero-cross-dehydrogenative coupling reactions of sulfoximines with diarylmethanes: a new route to N-alkylated sulfoximines.

An efficient iron-catalyzed C-N bond formation by hetero-cross-dehydrogenative coupling (CDC) between sulfoximines and diarylmethanes is described. The reaction shows good functional group tolerance and provides N-alkylated sulfoximines in moderate to good yields.
