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

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
