Synthesis of new functionalized aminomethylphosphonites and their derivatives

N-Benzyl and N-aryl bis(phospha-Mannich adducts): Synthesis and catalytic activity of the related bidentate chelate platinum complexes in hydroformylation

“…The double KabachnikeFields condensation made available lipophilic derivatives [15]. The use of phosphorous acid as the P-reactant led to bis(phosphonic acids) [16,17]. Bis(phosphinoxido)derivatives were synthesized via a surprising methylene insertion reaction into a PeN bond followed by oxidation [18].…”

Synthesis of new types of N,N‐disubstituted aminomethylspirophosphoranes

“…We realized another interesting route for the synthesis of several aminomethylspirophosphoranes via the interaction of the recently available O,O-diethyl aminomethylphosphonites [13] with ethylene glycol under mild conditions. So, the mixing of the reagents in methylene chloride was accompanied by the rapid formation of hydrogen to give the spirophosphoranes 3, 5, and 6 in high yields (Eq.…”

“…The 1 H, 13 C, and 31 P NMR spectra were recorded on a Varian VXR-400 and Bruker Avance-400 spectrometer (400, 100, and 162 MHz, respectively) in C 6 D 6 or CDCl 3 (1)(2)(3)(4)(5)(6)(7)(8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18). All reactions were carried out under dry argon in anhydrous solvents.…”

Catalyst-Free and Selective C–N Bond Functionalization: Stereospecific Three-Component Coupling of Amines, Dichloromethane, and >P(O)H Species Affording α-Aminophosphorus Compounds

“…N,N-bis(diethoxyphosphinoylmethyl)-N-methylamine (1e). 18 Following the general procedure, the crude product was purified by preparative GPC using CHCl 3 as eluent to afford a colorless liquid. Yield: 63.7 mg, 77%.…”
