Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments.Introducing a new discovery about 17261-28-8, Name is 2-(Diphenylphosphino)benzoic acid, name: 2-(Diphenylphosphino)benzoic acid.
The diphosphine anhydride (PCO)2O was prepared in high yield by DCC coupling of 2-diphenylphosphinobenzoic acid. The diphosphine oxidatively adds to Fe(0) carbonyls to give the acyl carboxylate Fe(PCO)(PCO 2)(CO)2 (1). The complex adopts a distorted octahedral geometry with trans phosphines and cis carbonyl ligands. Treatment of Ni(COD)2 with (PCO)2O afforded the square-planar acyl carboxylate Ni(PCO)(PCO2) (2) with trans phosphine ligands. Upon treatment with PMe3, 1 gives the monocarbonyl Fe(PCO)(PCO 2)(CO)(PMe3), whereas 2 and PMe3 react to give the pentacoordinate adduct 2PMe3. Both 1 and 2 give 1:1 adducts with B(C6F5)3 (BPhF3). Crystallographic analysis revealed that the borane binds to the noncoordinated carboxylate oxygen in both cases. The value of nuCO for the carboxylato ligand decreased by 45 cm-1, and in the case of 1BPh F3, nuCO for the CO ligands increased by 15 cm-1. In solution, 1BPhF3 exists as an equilibrium mixture of three isomers, including a kinetic isomer and another isomer that selectively crystallizes.
Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law.Formula: C19H15O2P. In my other articles, you can also check out more blogs about 17261-28-8
