Did you know?
In chemistry a phosphine imide (sometimes abbreviated to phosphinimide) also known as a iminophosphorane is a functional group with the formula R3P=NR. While structurally related to phosphine oxide its chemistry has more in common with phosphonium ylides. Anions of this group, with the … Zobacz więcej Phosphine imides can be isolated as intermediates in the Staudinger reaction and have also been prepared by the action of hydroxylamine-O-sulfonic acid on phosphines, proceeding via a p-aminophosphonium … Zobacz więcej The functional group will readily hydrolyse to give a phosphine oxide and an amine R3P=NR' + H2O → R3P=O + R'NH2 Phosphinimide ligands Zobacz więcej • Aminophosphine • Phosphazene Zobacz więcej Witryna手性二胺,chiral diamine 1)chiral diamine手性二胺 1.The water-soluble chiral diamine ligands are prepared by sulphonation reaction.通过磺化反应合成了水溶性手性二胺配体,用1H-NMR,13C NMR,IR分析表明两种构型的手性二胺的磺化反应都发生在邻位,并寻求了合成水溶性手性配体的最佳途径。 2.At present, studies on and applications of chiral ...
Witryna9 cze 2009 · Splendid isolation: Monomeric phosphazene F 2 PN (1 A 1) was prepared for the first time through irradiation of F 2 PN 3 in an argon matrix with an ArF excimer laser (λ=193 nm). Upon subsequent irradiation with a high‐pressure mercury arc lamp (λ=255 nm), F 2 PN undergoes a 1,2‐fluorine shift to give iminophosphane cis‐FP NF. WitrynaThe resulting three membered ring system can be considered as a complex of two iminophosphanes. Contrary to the classical cyclopropanation reaction, in the pseudo‐carbene iminophosphane the corresponding [2 + 1] reaction is only slightly exothermic, as established by ab initio calculations at the SCF/CEPA‐1 and the …
