Two series of bis(α-aminophosphonates) were synthesized by one-pot three-component reactions using 4-phenylenediamine, an aldehyde (2 equiv) and a phosphite (2 equiv), or terephtalaldehyde, an amine (2 equiv), and a phosphite (2 equiv) together with propy

Zirconocene bis(perfluorobutanesulfonate) [Cp2Zr(OSO 2C4F9)2·2H2O] was successfully synthesized by treatment of Cp2ZrCl2 with C4F9SO3Ag, and was found to have the nature of air-stability, water tolerance, high thermal stability and strong Lewis acidity. This complex showed high catalytic efficiency for the synthesis of α-aminophosphonates via Kabachnik-Fields reaction of aldehydes/ketones, amines and diethyl phosphite under mild and solvent-free conditions. Furthermore, it can be reused without loss of activity in a test of five cycles. Compared with our previously reported complex of Cp2Zr(OSO 2C8F17)2·3H 2O·THF, this complex showed better catalytic activity.

NbCl5 has been found to be a very effective catalyst for the synthesis of a variety of α-aminophosphonates through the Kabachnik-Fields reaction of carbonyl compound, amine and diethyl phosphite under solvent-free conditions. Copyright
Xanthan sulfuric acid as an efficient biodegradable and recyclable catalyst for the one-pot synthesis of α-amino phosphonates
Sun, Guo-Ying,Hou, Jun-Tao,Dou, Jing-Jie,Lu, Jun,Hou, Yong-Jie,Xue, Tuo,Zhang, Zhan-Hui
experimental part, p. 1315 - 1320 (2011/10/07)
A convenient and efficient procedure for the synthesis of α-amino phosphonates by a one-pot, three-component condensation of aldehydes, amine, and diethyl phosphite in the presence of xanthan sulfuric acid as a bio-supported catalyst under solvent-free conditions has been developed. A wide range of α-amino phosphonates have been obtained in high to excellent yields. Furthermore, the catalyst can be recovered simply and reused several times in subsequent reactions.
Micellar solution of sodium dodecyl sulfate (SDS) catalyzes Kabacknik-Fields reaction in aqueous media
Sobhani, Sara,Vafaee, Asieh
experimental part, p. 1909 - 1915 (2009/12/30)
A new, convenient and high-yielding procedure for the one-pot synthesis of diethyl α-aminophosphonates from aldehydes, amines and diethyl phosphite (Kabacknik-Fields reaction) in SDS micellar solution in aqueous media is described. The synthesis of aaminophosphonates in the present study represents a three-component reaction in which no intermediate formation of either an imine or α-hydroxyphosphonate was observed.

Rezaei, Zahra,Firouzabadi, Habib,Iranpoor, Nasser,Ghaderi, Abbas,Jafari, Mohammad Reza,Jafari, Abbas Ali,Zare, Hamid Reza
experimental part, p. 4266 - 4275 (2009/12/24)
In this study, we used a solution of FeCl3 in THF to facilitate the Mannich-type reaction of aldehyde, amine and phosphite compounds to form corresponding α-aminophosphonates in a one-pot, three-component reaction. Selected α-aminophosphonates
An eco-friendly procedure for the efficient synthesis of dialkyl α-aminophosphonates in aqueous media

A new, convenient and high yielding procedure for the preparation of diethyl α-aminophosphonates in water by one-pot reaction of aldehydes, amines, tri/dialkyl phosphites in the presence of a low catalytic amount of [Cu(3,4-tmtppa)](MeSO4)4 (0.16 mol%) as a highly stable and re-usable catalyst is described.
The stereochemical behavior of terephthalic schiff bases in addition of dialkyl or diaryl phosphites
Lewkowski, Jaroslaw
, p. 179 - 195 (2007/10/03)
Addition of dialkyl (or diaryl) phosphites to N-alkyl terephthalic Schiff bases led exclusively to a meso-form but addition to N-aryl terephthalic Schiff bases depended on the substituent of the aryl group. Semi-empirical calculations were involved to fin
