Transition Metal-Activated Organic Compounds, XXXVII. - A Novel Reaction of Aldehydes and Ketones: Synthesis and Spectroscopic Investigation of α-Phosphinioalkoxy Transition Metal Complexes

By treatment of aldehydes and ketones with one mole equivalent of a Lewis acid (TiCl4, NbCl5, TaCl5) and one mole equivalent of PPh3, or in one case of Ph2PCH2CH2PPh2, the aldehyde derivatives 1CH(P+Ph2R2)-OMCln>Cl- (4-8; M = Ti, Nb, Ta; R2 = Ph or CH2CH2Ph2) and the ketone derivatives 1R2C(P+Ph3)-ONbCl4>Cl- (9-10) were prepared.Complexes 4-10 were isolated as air- and water-sensitive solids.According to the NMR spectra some of the obtained aldehyde derivatives 4-8 exist in solution as a mixture of isomers or oligomers, whereas the ketone derivatives 9 and 10 form in solution an equilibrium with the free ketone and the complex NbCl5*PPh3.The chloride ion of 4-10 is perhaps coordinated to the metal.
