Syntheses and structures of tungsten o-(Diphenylphosphino)benzaldehyde complexes bearing pi-bonded aldehyde groups
Reaction of the bidentate ligand Ph2P(o-C6H4)C(=O)H (abbreviated as PCHO) with W(CO)3(eta3-(MeNCH2)3) at room temperature affords W(CO)3(eta1-PCHO) (eta3-PCHO) (1), which subsequently loses a carbonyl ligand to give W(CO)2(eta3-PCHO)2 (2). Further treatment of 2 with PCHO in refluxing benzene results in carbon – carbon coupling of the PCHO ligands to produce W(CO)(eta3-PCHO)(eta3-(PCHO)2) (3). The structures of 1-3 have been determined by an X-ray diffraction study. The PCHO ligands in these compounds act as chelating phosphine-aldehydes with the aldehyde groups coordinating in a pi fashion.
Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.50777-76-9, you can also check out more blogs about50777-76-9
