Usage

General Description

Tripropyl phosphite is a chemical compound with the formula C9H21O3P. It is a colorless liquid with a mild, fruity odor and is used primarily as a chemical intermediate in the production of various chemical compounds and polymers. It is commonly used as a reducing agent in organic synthesis and as a stabilizer in the production of PVC. Tripropyl phosphite is also used as a flame retardant in plastics and as an antioxidant in various industrial applications. It is considered to be a relatively low-toxicity substance, but proper safety measures should still be followed when handling and using it.

Synthesis and crystal structure of some phosphite, thiophosphite, and amidophosphite copper(I) halide complexes

Some Cu(I) halides complexes based on P(III) acid esters, {[(RE) 3PCuBr] (where E = O, N, S); R = n-Pr, i-Pr, Et2N} were obtained and characterized using IR, 31P NMR spectroscopy, and single crystal X-ray diffraction. The comparative structural characteristics of complexes with various donor atoms (E = O, N, S) are analyzed.

Synthesis and reactivity of substituted α-carbonylphosphonites and their derivatives

Convenient methods for the synthesis of functionalized organophosphorus compounds containing carbonyl groups as well as di- or trialkoxymethyl fragments attached to phosphorus, and their derivatives, starting from the available derivatives of trivalent phosphorus acids, are proposed, and some properties of the new functionalized organophosphorus compounds are presented. So, the alkylation and acylation reaction of (dialkoxymethyl) phosphonites and their analogs have been studied. It is found that the Arbuzov rearrangement of these compounds was accompanied by the phosphorus-carbon bond cleavage with unique retention of the three-coordinate phosphorus.

Electrochemical Oxidation of Metal Dialkyl Phosphites and Their Reaction with Halogens

Electrochemical oxidation of sodium dialkyl phosphites with alkyl radicals of normal structure leads to formation of tetraalkyl pyrophosphites as the main products, while electrochemical oxidation of litium dialkyl phosphites and sodium salts with branched alkyl radicals yields tetraalkyl hypophosphates. The reaction of metal dialkyl phosphites with halogens leads to analogous results.
