Li, He published the artcileAn improved method for the synthesis of phenylacetic acid derivatives via carbonylation, HPLC of Formula: 620-20-2, the publication is Journal of Chemical Research (2019), 43(11-12), 548-552, database is CAplus.
A series of phenylacetic acid derivatives RCH2CO2H [R = 2-ClC6H4, 4-MeC6H4, 2,4-Cl2C6H3, etc.] was synthesized via bistriphenylphosphine palladium dichloride catalyzed carbonylation reaction of benzyl chloride derivatives in presence of tetraethylammonium chloride and sodium hydroxide as reagents and xylene as solvent at 80°C under a CO atm. 2,4-Dichlorophenylacetic acid was obtained in a maximum yield of 95% from 2,4-dichlorobenzyl chloride using the same reaction system.
Journal of Chemical Research published new progress about 620-20-2. 620-20-2 belongs to chlorides-buliding-blocks, auxiliary class Chloride,Benzyl chloride,Benzene, name is 3-Chlorobenzylchloride, and the molecular formula is C7H6Cl2, HPLC of Formula: 620-20-2.
