Le, Zhengjie published the artcilePalladium-Catalyzed Carbonylative Synthesis of 1,5-Dihydro-2H-pyrrol-2-ones from Propargyl Amines and Benzyl Chlorides, Quality Control of 939-99-1, the publication is Advanced Synthesis & Catalysis (2021), 363(7), 1878-1881, database is CAplus.
A palladium-catalyzed double carbonylation of propargyl amines and benzyl chlorides employing benzene-1,3,5-triyl triformate (TFBen) as the CO source was developed. By using this protocol, various 1,5-dihydro-2H-pyrrol-2-ones I [R = Ph, 4-FC6H4, 3-thienyl, etc.; R1 = Ph, 4-MeC6H4, 4-ClC6H4, etc.] were produced in good yields.
Advanced Synthesis & Catalysis published new progress about 939-99-1. 939-99-1 belongs to chlorides-buliding-blocks, auxiliary class Fluoride,Chloride,Benzyl chloride,Benzene, name is 1-(Chloromethyl)-4-(trifluoromethyl)benzene, and the molecular formula is C8H6ClF3, Quality Control of 939-99-1.
