The Reactive Behaviour of Methyl Substituted Propenoyldiphenylphosphanes and their Oxides

The action of RC(O)Cl (1a – e) on (CH3)3SiPPh2 generates only the propenoyldiphenylphosphanes RC(O)PPh2 2c – e, in the case of 2a, b polymerization and decomposition, respectively, occurs immediately.The reactive phosphane oxides RC(O)P(O)Ph2 (3d, e) and the esters Ph2(O)P-CHR1-CR2=COC(O)R (4bb’, cc’) are obtained from 1b – e and CH3OPPh2.The mechanism for the formation of 4bb’ is proved for the example of 1b.As a detectable intermediate the enol ether Ph2(O)P-CHCH3-CH=COCH3 (5b’) appears which reacts with additional 1b to give 4bb’.The structures of the newly prepared compounds are discussed on the basis of their mass, IR, and NMR spectra.
