2557-70-2 Usage

General Description

2-(Trifluoroacetyl)pyrrole, an α,α,α-trifluoromethyl ketone is a 2-substituted pyrrole derivative. It has been synthesized by reacting pyrrole with trifluoroacetic anhydride in benzene at 0°C. Its enantioselective hydrogenation to form corresponding alcohol using 5wt.% Pt/Al2O3 catalyst chirally modified by new synthetic chiral amines has been investigated.

Check Digit Verification of cas no

The CAS Registry Mumber 2557-70-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,5,5 and 7 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 2557-70:
(6*2)+(5*5)+(4*5)+(3*7)+(2*7)+(1*0)=92
92 % 10 = 2
So 2557-70-2 is a valid CAS Registry Number.

A closer insight into the mechanism operating in the trifluoroacetylation of pyrrole. New trifluoromethyl pyrroylmethane discovered

Peláez,Burgos Paci,Argüello

, p. 1934 - 1938 (2009)

A former studied reaction of acetylation of pyrrole was revisited and this allowed the identification of new compounds and the isolation and characterization of a very stable solid (2,2′,2″-(2,2,2-trifluoroethane-1,1,1-triyl)tris(1H-pyrrole)). All these m

Catalytic asymmetric hydrogenation of α-CF3- or β-CF3-Substituted acrylic acids using Rhodium(I) complexes with a combination of chiral and achiral ligands

Dong, Kaiwu,Li, Yang,Wang, Zheng,Ding, Kuiling

supporting information, p. 14191 - 14195 (2014/01/06)

Only the mixture works! Acrylic acid derivatives with CF3 substituents in α or β position were efficiently hydrogenated in the presence of a RhI complex with a chiral secondary phosphine oxide (SPO; see scheme) and an achiral Ph3P as ligands. The corresponding propanoic acid derivatives were obtained with generally high conversion (>99 %) and high enantioselectivity (92->99 %). Copyright
