Truchan, N; Jandl, C; Pothig, A; Breitenlechner, S; Bach, T in [Bach, Thorsten] Tech Univ Munich, Dept Chem, Lichtenbergstr 4, D-85747 Garching, Germany; Tech Univ Munich, Catalysis Res Ctr, Lichtenbergstr 4, D-85747 Garching, Germany published Access to Biphenyls by Palladium-Catalyzed Oxidative Coupling of Phenyl Carbamates and Phenols in 2019, Cited 69. The Name is m-Methoxyphenol. Through research, I have a further understanding and discovery of 150-19-6.
The oxidative cross-coupling of phenols (3 equiv) to various substituted phenyl N,N-diethylcarbamates was explored with a variety of substrates. Pd(OAc)(2) was employed as the catalyst (20 mol%) and K2S2O8 as the stoichiometric oxidant in trifluoroacetic acid as the solvent (50 degrees C, 2 h). Carbamates without or with a substituent on the phenyl ring (Me, Ph, Cl, OMe) underwent the reaction unless the phenyl substituent was too strongly electron withdrawing (CN). Cross-coupling occurred exclusively in theorthoposition relative to the carbamate group. The regioselectivity at the phenol (orthoorparato hydroxy) was mainly determined by steric factors. Yields up to 60-70% were achieved for specific carbamate/phenol combinations.
