Polyfunctional phosphine ligands. Preparation of 4'-formyl-2-diphenylphosphinoacetophenone and its coordination properties
The trifunctional ligand C(O)CH2PPh2 (5) has been prepared in four steps (overall yield 50percent) starting from terephthalaldehyde mono-(diethylacetal) (1): reaction of 1 with CH3MgBr gives C6H4>CH(OH)CH3 (2).This is oxidize
Synthesis and coordination properties of novel polyfunctional phosphine ligands
4′-formyl-2-diphenylphosphino-acetophenone 5 has been prepared in four steps (50%) starting from terephtalaldehyde mono-(diethylacetal) 1. Condensation of 5 with the para-substituted anilines H2NA-i gives quantitatively the phosphine-imines 6-8
