Additions of aromatic imines at the ortho carbon-hydrogen bonds to olefins were catalyzed by ruthenium complexes affording 1:1 addition products in good to excellent yields. In some cases, a by-product arising from dehydrogenative coupling was also obtained. Both aldimines and ketimines reacted well. Olefins such as styrene, 3,3-dimethyl-1-butene, and ethylene yielded corresponding products in good

The photoreductive coupling of pyridine-, arene- and alkynecarboxaldimines is a very convenient procedure for the preparation of vicinal diamines in good to excellent yields. The usual trend gave an excess of meso diamine, which enhances the usefulness of this method. The procedure tolerates bulky groups such as tert-butyl and diphenylmethyl on the nitrogen atom.
