Preparation of acid-functionalized poly(phenylene oxide)s and poly(phenylene sulfone) and their proton conductivity

A series of highly acid-functionalized poly(phenylene oxide)s and poly(phenylene sulfone) were prepared and proton conductivity in their membranes is discussed. Phosphorylated poly(phenylene oxide)s were prepared via the oxidative polymerization of phosph

Synthesis and hydrolysis of a phenylalanyl adenylate pentacoordinated phosphorane

Amino acid-nucleotide conjugates have important biological functions and therapeutic applications. For example, aminoacyl adenylates are key intermediates in aminoacyl tRNA synthetase reactions. They may also be involved in the prebiotic synthesis of polypeptides. Finally, various amino acid carbomethoxy aryl phosphoramidates of nucleotide prodrugs may be activated through a mechanism involving a pentacoordinated phosphorane intermediates. In order to understand better the chemistry of these compounds, a phenylalanyl adenylate pentacoodinated phosphorane has been synthesized in 72% yield and its decomposition in aqueous solution studied. Hydrolysis gave 2′,3′-O-isopropylidene adenosine 5′-monophosphate, 2′,3′-O-isopropylidene adenosine, and phenylalanine. The results provide model chemistry for the enzymatic degradation mechanism of antiviral aryl amino acid phosphodiester amidates in cells, which leads to their activation.

PYROCATECHOL CYCLOPHOSPHATES IN REACTIONS WITH PROTON-CONTAINING NUCLEOPHILES

A general principle of the hydrolysis and alcoholysis of cyclophosphates of pyrocatechol and its derivatives is facile ring opening and anomalously facile cleavage of the P-O (P-N) bond to give, in all of the indicated cases, phosphoric acid 2-hydroxyphenyl phosphate.The latter is predetermined by the formation of a hydrogen bond with the participation of the phenolic hydroxy group of the 2-hydroxyphenyl radical.

Organophosphorus Antioxidants. II. Kinetics and Mechanism of the Decomposition of Alkylhydroperoxides by Esteramides of Phosphorous and Phosphoric Acid

The reaction mechanism of 2-amido-1,3,2-benzodioxaphospholes (1) with cumyl and t-butylhydroperoxide has been studied kinetically by means of 31P-n.m.r. and e.p.r. spectroscopy and high pressure liquid chromatography. 1 reacts with cumyl hydroperoxide to give the corresponding 2-oxides (2) which with more hydroperoxide and/or water form the phosphate esters 7 and 8.These acidic phosphates decompose cumyl hydroperoxide catalytically giving phenol and aceton.All amides (1) react with t-butyl hydroperoxide stoichiometrically to give t-butanol.The ionic mechanism of hydroperoxide decomposition is accompanied in a minor proportion by a homolytical one.
