The Kabachnik–Fields condensation was extended using secondary phosphine oxides, such as dibenzylphosphine oxide and bis(4-methylphenyl)phosphine oxide as the P-reactant in reaction with formaldehyde and different primary amines. Besides the α-aminophosphine oxides, the corresponding bisproducts, N,N-bis(phosphinoylmethyl)amines were also synthesized under appropriate conditions. The bis(phosphinoyl)amines
Kabachnik-Fields缩合反应使用仲膦氧化物进行扩展,例如二苄基膦氧化物和双(4-甲基苯基)膦氧化物作为P-反应物,与甲醛和不同的伯胺反应。除了α-氨基膦氧化物外,相应的双产物N,N还在适当条件下合成了-双(膦酰基甲基)胺。然后在双脱氧后将双(膦酰基)胺转化为环铂络合物。使用有效核心电位(ECP)基础集(SDD)通过B3LYP / 6-31G(d,p)计算评估了使用双齿P-配体的络合反应的能量学对取代基的依赖性以及一些络合物的立体结构。通过X射线分析研究了几种环型Pt物种的晶体结构。在加氢甲酰化中研究了合成的配合物的催化活性。
