ZnCl2 supported on silica gel has shown to be an effective catalyst for transesterification of the organophosphate insecticide, paraoxon, in the presence of 2-phenylethanol. The kinetics of the reaction in acetonitrile was studied. Formation of the product diethyl 2-phenylethyl phosphate was confirmed by 31P NMR.
Phosphorylation of amines, alcohols, and sulfoximines are accomplished using molecular iodine as a catalyst and H2O2 as the sole oxidant under mild reaction conditions. This method provides an easy route for synthesizing a variety of phosphoramidates, phosphorus triesters and sulfoximine-derived phosphoramidates which are of biological importance.
在温和的反应条件下,使用分子碘作为催化剂并使用H 2 O 2作为唯一的氧化剂,可以实现胺,醇和亚磺酰亚胺的磷酸化。该方法提供了一种容易的途径,用于合成具有生物学重要性的多种氨基磷酸酯,三酯磷和源自亚磺酰亚胺的氨基磷酸酯。

rac-secondary phosphine oxides via the enantioselective P-benzylation process catalyzed by the palladium/Xiao-Phos was designed. Both, tert- and sec-phosphine oxides were delivered in good yield and excellent enantiopurity (selectivity factor up to 226.1). The synthetic utilities are further demonstrated by the facile preparation of several P-chiral compounds, precursors of bidentate ligands, and transition

(β-Arylethyl)phosphorochloridates decompose easily yielding 1-chloro-2-arylethanes and/or arylethylenes, presumably via the concerted P-Cl fission and the expulsion of metaphosphate-like species.

Rateconstants for the migration of a series of p,p-disubstituted β-(diarylphosphatoxy)alkyl migrations have been determined in benzene at reflux by competition against the benzeneselenol clock reaction. There is a strong linear correlation of log(k) with the Hammett σp but not with various σ• parameters indicating that the migration occurs through a highly polarized transition state resembling an
