Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments.Introducing a new discovery about 13406-29-6, Name is Tris(4-(trifluoromethyl)phenyl)phosphine, Formula: C21H12F9P.
The stoichiometric oxidations of some P(p-X-C6H4)3 compounds (X = OMe, Me, H, F, Cl and CF3), AsPh3 and SbPh3 by trans-Ru(VI)(TMPO)2 (1) in benzene solution generate the corresponding oxides and Ru(II)(TMP)(L) species (L = P(p-X-C6H4)3, AsPh3, SbPh3). Stopped-flow kinetic data are consistent with a mechanism involving formation (within a k1 step) of Ru(IV)(TMP)(O)(OL) which then reversibly dissociates the OL ligand to generate Ru(IV)(TMP)(O); this disproportionates to Ru(VI)(TMP)(O)2 and Ru(II)(TMP), which forms Ru(II)(TMP)(L). deltaH1(+) values for the phosphine systems vary from 18 to 21 kJ mol-1, increasing with decreasing electron density at the phosphorus, while DeltaS1(+) values become more favorable (-94 to -78 J mol-1 K-1) with increasing molecular mass of the substituent. Preliminary kinetic data on the O2-oxidations of the substrates catalyzed by (1) under 1 atm of air are presented.
Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law.Formula: C21H12F9P. In my other articles, you can also check out more blogs about 13406-29-6
