General Description

5,5-dimethyl-2-phenoxy-1,3,2-dioxaphosphorinane 2-oxide is a chemical compound that belongs to the class of organophosphate insecticides. It is commonly used for controlling a wide range of pests in agriculture. 5,5-dimethyl-2-phenoxy-1,3,2-dioxaphosphorinane 2-oxide works by inhibiting the action of an enzyme called acetylcholinesterase, which is essential for nerve function in insects, causing paralysis and ultimately death. Due to its effectiveness in pest control, it is widely used in agricultural practices. However, it is important to handle this compound with care as it is toxic to humans and other non-target organisms.

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.

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.
