GRAPHICAL ABSTRACT

ABSTRACT

1,3-Diol reacts with phosphorus trichloride to produce diastereomeric 1,3,2-dioxaphosphorinanes. To find the predominant conformations, the influence of the diol precursors is studied and density functional theory calculation (DFT) is used. Then, hydrolysis of chlorophosphite leads to two cyclodialcoxyphosphites which are identified by NMR (31P, Citation1 H, 13C, MR-SM). Also, the steps of synthesis of hydrazone 1-(5,5-diethyl-2-oxo-1,3,2-dioxaphosphoranyl)-3-phenyl-propanone are studied by 31P NMR.

Résumé

La conformation de départ du 1,3-diol influe sur la conformation des dérivés de 1,3,2-dioxaphosphorinane. En effet, l'addition du 1,3-diol sur le trichlorure de phosphore fournit un chloro-phosphite sous forme d'un mélange de diastéréoisomères. L'hydrolyse des deux chloro-phosphites conduit à deux cyclodialcoxyphosphites qui sont identifiés par RMN (31P, 1H, 13C, GC-MS). Une étude de la synthèse de l'hydrazone β–phosphonatée est suivie par RMN du phosphore-31.
