摘要: Abstract 4′-formyl-2-diphenylphosphino-acetophenone 5 has been prepared in four steps (50%) starting from terephtalaldehyde mono -(diethylacetal) 1 . Condensation of with the para -substituted anilines H 2 NA-i gives quantitatively phosphine-imines 6–8 Phosphines 4–6 instantaneously react Pd II (acac) to yield bis-enolato complexes cis -[Pd {[4′-(R)C 6 4 ]C(O)=CHPPh } ] (R=CH(OC ) , CH(O), CH=NA-12).
