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. Phosphines 4-6 instantaneously react with Pd(II)(acac)2 to yield the bis-enolato complexes cis-[Pd(II)[4'-(R)C6H4]C(O)=CHPPh2}2] (R=CH(OC2H5)2, CH(O), CH=NA-12).
