Niederer, Kyle A. published the artcileOxidative photocatalytic homo- and cross-coupling of phenols: Nonenzymatic, catalytic method for coupling tyrosine, Quality Control of 121-00-6, the main research area is phenol homo cross coupling oxidative photocatalytic method safety eyewear; oxidation potential nucleophilicity homo cross coupling reaction mechanism; tyrosine coupling cyclic voltammetry fluorescence quenching crystal structure; Oxidative coupling; cross-coupling; phenol coupling; photocatalysis; tyrosine dimerization.
An oxidative photocatalytic method for phenol-phenol homo- and cross-coupling is described, and isolated yields of 16-97% are obtained. Measured oxidation potentials and computed nucleophilicity parameters support a mechanism of nucleophilic attack of one partner onto the oxidized neutral radical form of the other partner. Our understanding of this model permitted the development of cross-coupling reactions between nucleophilic phenols/arenes and easily oxidized phenols with high selectivity and efficiency. A highlight of this method is that one equivalent of each coupling partner is utilized. Building on these findings, a nonenzymic, catalytic method for coupling tyrosine was also developed. Due to the high intensity of the light source it is highly recommended that impact resistant sunglasses be worn when placing a reaction in the photochem. bay.
