Two phosphorus-containing hydrazines, namely morpholin-4-ylphosphoramidic acid diethyl ester (1a) and (2,2,6,6-tetramethylpiperidin-1-yl)phosphoramidic acid diethyl ester (2a), have been synthesized. The corresponding hydrazyl radicals (1b and 2b) have been obtained, by in situ oxidation, and their properties have been investigated by...

Phosphoramidic acid monoesters as phosphorylating agents: steric effects and reluctance to form monomeric metaphosphate intermediates.

Chemical communications (Cambridge, England)

The formation of phosphate diesters (RO)(2)P(X)OH (R = Et, Pr(i) or Pr(i)(2)CH) by phosphorylation of ROH with ROP(X)(NPr(i)(2))OH is insensitive to steric effects when X = S but not when X = O; this is consistent with a unimolecular...

Luminescence property of phosphoramidic acid oligomer nanodots in aqueous solution.

Spectrochim Acta A Mol Biomol Spectrosc. 2021 Mar 05;248:119261. doi: 10.1016/j.saa.2020.119261. Epub 2020 Nov 30.

Luminescent polymer dots have showed great potential applications in chemical sensing and bioimaging. Herein, phosphoramidic acid oligomers in aqueous solution can form nanodots (ONDs) with mean diameter of 50 ~ 60 nm. The ONDs display blue fluorescence of excitation-dependence...
