Reaction of Trichloro(o-phenylenedioxy)phosphorane with 1,2-Alkadienylphosphonates

Trichloro(o-phenylenedioxy)phosphorane reacts with 1,2-alkadienylphosphonates with selective replacement of the alkoxy group in the phosphinoyl moiety, yielding the corresponding 1,2-alkadienylchlorophosphonates and o-phenylene chlorophosphate

On the mechanism of acetone and diacetyl reactions with halogenophosphoranes

In this study the interaction of acetone and diacetyl with pyrocatecholtrihalogenophosphoranes (PTHP) containing a five-membered cycle which improves the stability of pentacoordinated phosphorus state was first observed. Using NMR spectroscopy technique the reaction of PTHP with acetone is shown to be a quantitative unidirectional process without formation of any stable intermediates. Unlike acetone, diacetyl interaction with phosphoranes results in formation of relatively stable pentacoordinated intermediates, the products of both carbonyl groups reaction

Peculiar features of reaction of 2-tert-butoxy-5,6-benzo-1,3,2-dioxaphosphinin-4-one with chloral. Steric structure of 2-chloro-3-trichloromethyl-6,7-benzo-1,4,2λ ⁵-dioxaphopshepin-5-one 2-oxide

The reaction of 2-tert-butoxy-5,6-benzo-1,3,2-dioxaphosphinin-4-one with chloral involves expansion of the six-membered heteroring to form 2-hydroxy-3-trichloromethyl-6,7-benzo-1,4,2λ 5-dioxaphosphepin-5-one 2-oxide as a single diastereomer. The product was chlorinated with thionyl chloride to obtain (RS,SR)-2-chloro-3-trichloromethyl-6,7-benzo-1,4,2λ 5-dioxaphosphepin-5-one 2-oxide
