Oxidative Cross-Coupling of N-(2′-Phenylphenyl)benzene-sulfonamides or Benzoic and Naphthoic Acids with Alkenes Using a Palladium-Copper Catalyst System under Air

N-(2′-Phenylphenyl)benzenesulfonamides react with acrylate esters accompanied via cleavage of the C-H bond at their 2′-position in the presence of a catalyst system of Pd(OAc)2 and Cu(OAc)2 and a base under air to produce 5,6-dihydro-5-(benzenesulfonyl)phenanthridine-6-acetate derivatives in high yields. The reactions of benzoic acid with butyl acrylate and styrene can also give 3-[(butoxycarbonyl)methyl]phthalide and 3-phenylisocoumarin, respectively.

One-step synthesis of isocoumarins and 3-benzylidenephthalides via ligandless pd-catalyzed oxidative coupling of benzoic acids and vinylarenes

A straightforward synthetic method for the preparation of isocoumarins and 3-benzylidenephthalides via C-H olefination and oxidative coupling of readily available benzoic acids and vinylarenes was developed. The directing effect of the substituents on the benzoic acid allows for the synthesis of both types of lactone in pure form.
