New approach to the synthesis of phosphorodichloridites, phosphorochloridites, and trialkyl phosphites

Different trivalent organophosphorus esters such as phosphorodichloridites, phosphorochloridites, and mixed trialkyl phosphites have been easily synthesized in good yields using a HCl-catalyzed reaction of the corresponding chlorophosphine and alkoxytrimethylsilane by mutual exchange of the alkoxy and chlorine ligand pIIICl/ROSiR′3; exchange reaction). Chemoselectivity of the exchange reaction with primary and secondary alkoxytrimethylsilanes, as well as with alkoxytrimethylsilanes and thioalkoxytrimethylsilanes, respectively, has also been examined. It has been also found that the substitution reaction of chlorophosphines with secondary amine occurs more rapidly than the exchange reaction with ROSiR′ 3.

Electrophilic Reactions of Activated Alkenes and Alkynes with Element Halides. III. Reaction of Activated Alkenes with Phosphorus Trihalides

Electrophilic substitution of the vinyl hydrogen atom in alkenyl alkyl ethers, 2-bromoethenyl alkyl ethers, and ketene acetals readily occurs under the action of phosphorus trihalides in the presence of an organic base to yield 70-98% of 2-alkoxy-, 2-alkoxy-1-bromo-, and 2,2-dialkoxyalkenylphosphonous dichlorides and dibromides. The reaction is regio- and stereospecific. A mechanism involving intermediate formation of a cyclic phosphiranium ion is proposed.
