Recently I am researching about KETONES; TRIFLUOROMETHYL; PERFLUOROALKYLATION; GENERATION; CHEMISTRY; ALDEHYDES; DERIVATIVES; CATALYSTS; REAGENTS, Saw an article supported by the Asahi Glass Foundation; JSPS KAKENHIMinistry of Education, Culture, Sports, Science and Technology, Japan (MEXT)Japan Society for the Promotion of ScienceGrants-in-Aid for Scientific Research (KAKENHI) [JP18H02553, JP18H04401]. Published in AMER CHEMICAL SOC in WASHINGTON ,Authors: Fujihira, Y; Hirano, K; Ono, M; Mimura, H; Kagawa, T; Sedgwick, DM; Fustero, S; Shibata, N. The CAS is 123-11-5. Through research, I have a further understanding and discovery of 4-Methoxybenzaldehyde. COA of Formula: C8H8O2
A simple protocol to overcome the explosive pentafluoroethylation of carbonyl compounds by HFC-125 is described. The use of potassium (K) bases with triglyme or tetraglyme as a solvent safely yields the pentafluoroethylation products in good to high yields. The experimental results suggest that an encapsulation of the K cation by glymes as K(glyme)(2) inhibits the contact between the K cation and the reactive anionic pentafluoroethyl counterion, preventing their transformation into KF and explosive tetrafluoroethylene (TFE). The generation of sterically demanding [K(G3)(2)](+) and [K(G4)(2)](+) is an effective way as an unstable pentafluoroethyl anion reservoir.
