PHOSPHORUS COMPOUND, USE THEREOF AND FLAME-RETARDANT POLYESTER FIBER

A phosphorus compound represented by the formula (I): wherein R1 and R2 are, the same or different, a hydrogen atom, a straight or branched-chain alkyl group having 1 to 6 carbon atoms or an aryl group having 6 to 12 carbon atoms which may be optionally substituted for an alkyl group having 1 to 4 carbon atoms, R3, R4, R5, R6 and R7 are, the same or different, a hydrogen atom or an aryl group having 6 to 12 carbon atoms which may be optionally substituted for an alkyl group having 1 to 4 carbon atoms, or R3 and R4, R4 and R5, R5 and R6 or R6 and R7 may form a 6 membered ring with carbon atoms wherein these groups bond a benzene ring provided that R3, R4, R5, R6 and R7 are not hydrogen atoms at the same time.

OZONIDES DU PHOSPHORE STABILITE ET STEREOCHIMIE

A phosphorus ozonides series was obtained by reaction of ozone on various phosphites (1a-13a).The oxidative addition of ozone leads to trioxophosphetane ring formation branched on pentacoordinated (1b-9b) or hexacoordinated (10b-13b) phosphorus.The stability and stereochemistry of these compounds were studied.

Organophosphorus Antioxidants. III. Kinetics and Mechanism of the Decomposition of Cumyl Hydroperoxide by Cyclic Phosphites

The reaction mechanism of cyclic esters of phosphorous acids I to VIII with cumyl hydroperoxide has been studied kinetically by means of 31P n.m.r. spectroscopy, high performance liquid chromatography and iodometric titration.The five-membered cyclic phosphites (I and II) react with cumyl hydroperoxide to give the corresponding phosphates (AI and AII) and cumyl alcohol.With more hydroperoxide or water they form the open chain phosphate esters (BI and BII) which decompose cumyl hydroperoxide catalytically giving phenol and acetone.Higher membered cyclic phosphites (III to VIII) react with cumyl hydroperoxide to give the corresponding phosphates and alcohol only.The mode of reaction depends on the hydrolysis behaviour of the cyclic phosphates (AI to AVIII).Only fivemembered cyclic phosphites which give easily hydrolyzable phosphates are able to decompose cumyl hydroperoxide catalytically.The nature of the exocyclic group in the phosphites has no influence on this behaviour.The kinetic parameters of the separate reaction steps are given.The ionic mechanism of hydroperoxide decomposition is accompanied by a homolytic one.

PHOSPHORUS OZONIDES ADDUCTS

Ozone reacts quantitatively on tricoordinated and dicoordinated Phosphorus Compounds.The oxidative addition of ozone on phosphites leads to pentacoordinated or hexacoordinated phosphorus adducts.These adducts are unstable in solution.The decomposition gives the corresponding phosphoric ester with singlet oxygen evolution.In the same conditions, ozone reacts on diphosphene and gives after double bond rupture an adduct: the metaphosphonate.The relative stabilities and oxidative properties are discussed.
