Diels-Alder cycloaddition as a new approach toward stable PC(sp3)P-metalated compounds.

A straightforward synthetic route toward a new family of dibenzobarrelene-based cyclometalated compounds is described.

Enantio- and regioselective heck-type reaction of arylboronic acids with 2,3-dihydrofuran.

Reported herein is a protocol for the enantioselective Pd(II)-catalyzed Heck-type reaction between arylboronic acids and 2,3-dihydrofuran. The highest chemical and optical yields were obtained when a Pd(OAc)2/(R)-MeO(biphenylphosphine) or a Pd(OAc)2/(R)-(2,2'-bis(diphenylphosphino)-1,1'-binaphthyl) catalyst and a Cu(OAc)2 reoxidant were employed.
