Palladium(II)-catalyzed meta-selective direct arylation of O-β-naphthyl carbamate

Chem Commun (Camb). 2015 Jan 25;51(7):1297-300. doi: 10.1039/c4cc07997c.

Abstract

Selective meta-arylation of O-β-naphthyl carbamate has been accomplished using Pd(OAc)2 as a catalyst precursor and K2S2O8 with AgOAc as the oxidant. A range of aryl boronic acids could be introduced in moderate to good yields. Mechanistic investigation shows that the carbamate substituent has a unique effect and the reaction undergoes an ortho-carbometallation/meta-direct arylation process.
