REACTION OF 2-TERT-BUTOXY-4,5-BENZO-1,3,2-DIOXAPHOSPHOLANE WITH TRIBROMOACETALDEHYDE

The reaction of 2-tert-butoxy-4,5-benzo-1,3,2-dioxaphospholane with tribromoacetaldehyde proceeds by initial halophilic attack on the bromine atom, leading to a product with retention of the P-Br bond (pyrocatechol bromophosphate) and an anion exchange product (pyrocatechol dibromovinylphosphate), and by initial attack at the carbon atom of the C=O group, which is accompanied by the elimination of isobutylene to form an α-hydroxyphosphonate.

INSERTION REACTIONS IN THE P-Hal BOND IN PHOSPHORANES. SYNTHESIS OF 1(1-HALOALKOXYL)PHOSPHORANES

Functionally substituted (1-haloalkoxy)phosphoranes were synthesized by the reactions of cyclic, bicyclic, and acyclic mono-, di-, and tri-halophosphoranes with chloral and bromal.
