Phosphonic dichloride
WebDec 14, 2024 · Abstract. We report a rapid, efficient, economic, environmentally benign, and easy to scale-up method for the synthesis of phosphonamide derivatives using ultrasound irradiation, under catalyst and solvent-free conditions starting from the corresponding amine and phenyl phosphonic dichloride. WebPhosphorus trichloride (PCl3) is a toxic and highly reactive reagent, which, on hydrolysis generates phosphorous acid (H 3 PO 3) and hydrochloric acid, exothermically. 23 It readily reacts with alcohols, in the presence of base, to produce phosphite triesters.

WebIn the case of the three samples, the highest HRC did not correspond to the lowest char yield, but vice versa. This may be due to the variable molecular weights that, in the crosslinking form with phenoxy-phosphonic dichloride, cause the samples to behave differently, without a clear hierarchy being established between the three samples. WebHere we demonstrate the stable covalent attachment of diamantane phosphonic dichloride on tungsten/tungsten oxide surfaces. X-ray photoelectron spectroscopy (XPS) and Fourier-transform infrared (FTIR) spectroscopy revealed that diamondoid-functionalized tungsten oxide films were stable up to 300–350 °C, a substantial improvement over ...
