A Co‐catalyzed effective transferhydrogenation of various α‐ketoesters and N‐cyclicsulfonylimides by safe and environmentally benign H2O as hydrogensource is described. The reaction used easily available and easy to handle zinc metal as a reductant. Interestingly, the catalytic system does not require ligand for reduction of N‐cyclicsulfonylimides.

The rhodium(III)‐catalyzed ring‐opening addition of the cyclic N‐sulfonyl ketimines with azabenzonorbornadienes via C−H activation was developed. The reactions afforded the corresponding 2‐aryldihydronaphthalenes derivatives in good yield (up to 98%) under redox‐neutral conditions.
