Han, Yi published the artcileThe protecting group enabled para-selective C-H benzylation of anilides via iron(II) catalysis: a convenient approach for the synthesis of triarylmethanes, Formula: C13H10F2, the publication is Organic Chemistry Frontiers (2020), 7(14), 1823-1827, database is CAplus.
A series of triarylmethanes I [R = H, 2-Me, 3-Cl, etc.; R1 = NHC(O)Me, NHC(O)C(Me)3, NHCO2CH2CH(Me)2, etc.; R2 = Me, Ph, 2-MeC6H4, etc.; Ar = Ph, 4-FC6H4, 4-EtC6H4, etc.] was synthesized via iron catalyzed para-selective C-H benzylation of iso-Bu Ph carbamates with diarylmethanes. Iso-Bu Ph carbamates were prepared using reaction of anilines and iso-Bu chloroformate. Preliminary mechanistic studies revealed that the iron(II) catalyst was essential and the use of the sterically demanding isobutoxy group led to high para-selectivity.
Organic Chemistry Frontiers published new progress about 457-68-1. 457-68-1 belongs to catalysis-chemistry, auxiliary class Fluoride,Benzene, name is Bis(4-fluorophenyl)methane, and the molecular formula is C13H10F2, Formula: C13H10F2.
