A mild, general and efficient hydrocyanation and hydroarylation of enamines catalyzed by Co(salen) complexes are described. Both reactions include regioselective C[sbnd]H bond formation of enamines, and the corresponding products are obtained in high yield. Hydroarylation critically discriminates the benzyl and benzoyl aromatic rings on nitrogen in cyclization step, and the corresponding isoindolinones including quaternary carbons are exclusively given.
Palladium-catalyzed oxidative activation of arylcyclopropanes

(Diagram presented) Palladium chloride-catalyzed intramolecular activation of electroneutral cyclopropane derivatives results in cleavage of the cyclopropane ring followed by formation of heterocyclic derivatives. Phenols, carboxylic acids, and amide groups were considered as substituents ortho to the cyclopropane ring in this catalytic activation chemistry. The regioselectivity observed in the case of amide-containing substrates was different from that of carboxylic acid-containing substrates, ruling out simple cyclopropane isomerization followed by a Wacker oxidation as the mechanistic pathway.
