IMPORTANCE OF AMINE HYDROHALIDES IN ALCOHOLYSIS OF PHOSPHOROUS ACID AMIDES

The data are presented on the rates of deuteromethanolysis of 2-fluoro-1,3,2-dioxaphosphorinane 1 in the presence of various bases differing in the basicity and of that of 2-amino-1,3,2-dioxaphosphorinanes 22-4 catalysed by hydrogen fluoride salts of different amines.The alcoholysis of the fluorophosphite 1 in the presence of imidazole, N-ethylaniline and 2,6-di-tert-butyl-4-methylpiridine proceeds slowly whereas alcoholysis of the amidoesters 3,4 catalysed by imidazole and N-ethylaniline hydrofluorides occurs rapidly even at room temperature.These data do not match the hypothesis that halophosphites are intermediates in the alcoholysis of amidophosphites in the presence of amine hydrohalides.

A New Method for Obtaining Isotopic Fractionation Data at Multiple Sites in Rapidly Exchanging Systems

A new method for rapidly and conveniently obtaining isotopic fractionation factors in dilute aqueous solutions of compounds containing rapidly exchanging OH, NH, and SH groups is described.Shifts in the positions of NMR peaks for spectroscopically observable nuclei induced by isotopic substitution are the basis of this procedure which has the unique capability of separately measuring the isotopic exchange constants simultaneously for several different groups in the same molecule.The results for a series of alcohols, amines, thiols, phenols, acids, and amides with use of 13C NMR spectroscopy are reported.Atypically low values of Kfrac are observed in several cases, indicating that there are strong internal hydrogen bonds in competition with those to water, yielding conformational information.

NUCLEOPHILIC ADDITION TO COORDINATED ALLYL LIGANDS. HETEROATOM NUCLEOPHILES WITH CATIONIC MOLYBDENUM COMPLEXES

The addition of the heteronuclear anions (methoxide, hydride, alkylnitronate and mercaptide) to a series of ?-allylmolybdenum cations, related to η5-C5H5Mo(CO)(NO)(η3-alyl)+ was examined.In each case, the adducts derived f
