Reference of 50777-76-9. Let’s face it, organic chemistry can seem difficult to learn. Especially from a beginner’s point of view. Like 50777-76-9, Name is 2-(Diphenylphosphino)benzaldehyde. In a document type is Article, introducing its new discovery.
Mono- and dinuclear oxidorhenium(V) complexes with hemiacetal ligands were isolated from a reaction of (NBu4)[ReOCl4] with a potentially tetradentate Schiff base prepared from (1R,2R)-cyclohexane-1, 2-diamine and (2-formylphenyl)diphenylphosphine in methanol. The hemiacetal is formed by solvolysis of first one imine functionality of the Schiff base, whereas the second remains intact. The resulting amine/iminophosphine coordinates as a tridentate N,N, P ligand in a dinuclear compound. Ongoing degradation of the Schiff base gives more hemiacetal (HL1a) and the final product, the monomeric complex [ReOCl(L1a)2] is formed. Cleavage of the organic framework is not observed during the reaction of (NBu4)[ReOCl4] with a related Schiff base derived from ethylene-1, 2-diamine and (2-formylphenyl)diphenylphosphine. The Schiff base reacts as a bis-bidentate N, P ligand and a dinuclear oxorhenium(V) compound with a central ethylene bridge is formed. Copyright
