N-Benzyl and N-aryl bis(phospha-Mannich adducts): Synthesis and catalytic activity of the related bidentate chelate platinum complexes in hydroformylation
The microwave-assisted double Kabachnik–Fields (phospha-Mannich) reaction of benzylamine and arylamines, two equivalents of paraformaldehyde and the P(O)H reagent, such as dialkyl phosphites, ethyl phenyl-H-phosphinate and diphenylphosphine oxide gave the bis(P(O)CH2)amine derivatives in good yields. The bis(diphenylphosphinoxido) derivatives were converted to the corresponding ring platinum complexes
Kabachnik-Fields reactions of a variety of amines, phospha-Michael additions to maleimide derivatives and alcoholysis of dialkyl phosphites were studied under microwave conditions.
