Metallation reactions of diphosphiranes: new access to ?- and ?-diphosphaallyl complexes

The metallation reactions of the functionalized diphosphiranes 1a,b, with the anionic metal transition complexes Na (M = Mo, W, or Co) afford ?- or ?-diphosphaallyl complexes depending on the substituents of the intracyclic carbon atom.The sa

DIPHOSPHIRANES: NEW PRECURSORS OF ?- or ?-DIPHOSPHAALLYL COMPLEXES.

The metalation reactions of the functionalized diphosphiranes 1a-b with the anionic metal transition complexes (M = Mo, W, Co) afford the ?- or ?-diphosphaallyl complexes (2 or 3, respectively) as function of the intracyclic carbon atom substituents.The t

Reactivity of functionalized diphosphiranes and 1,3-diphosphapropenes towards Grignard reagents

The reaction of saturated and unsaturated organomagnesium compounds with the monohalogenated diphosphiranes, 1a-b, and their isomers, the 1,3-diphosphapropenes, 2a-b, leads to a series of substituted 1,3-diphosphapropenes and 1,3-diphosphadienes 4-8 (a-b), but with the dihalogeno-derivatives 1c-d and 2c-d, it gives quantitative yields of 1,3-diphospha-allene 9.The reaction occurs via an anionic ring-opening involving an allylic anion intermediate 11a-b, detected by 31P NMR.

A NEW DIRECT METHOD FOR INTRODUCING 2-(2,4,6-TRI-t-BUTYLPHENYL)-2-PHOSPHAVINYLIDENE GROUP. FORMATION OF 1-PHOSPHA- AND 1,3-DIPHOSPHA-ALLENES

2-Phosphavinylidene group was introduced by the corresponding trimethylsilyllithio compound toward carbonyl compounds to give 1-phosphaallenes, whereas 1,3-diphosphaallene was prepared by the reaction of 1-chloro-2-phosphavinyllithium toward a phosphinous chloride followed by dehydrochlorination.

A CONVENIENT NEW ROUTE FROM DIPHOSPHENE TO 1,3-DIPHOSPHA-ALLENE AND DYNAMIC NMR STUDIES OFF THE 2,4,6-TRI-t-BUTYLPHENYL DERIVATIVE

Addition of dihalocarbenes to a diphosphene gave diphosphiranes which undergo rearrangement on treatment with alkyllithium reagents to afford 1,3-diphospha-allene; dynamic NMR studies on the allene are described.

RING-OPENING OF DIPHOSPHIRANES LEADING TO 1,3-DIPHOSPHAALLENE

The 3,3-dihalogeno-1,2-diphosphiranes 1(a-b) and its photochemical isomers, the 2,3-dihalogeno-diphosphapropenes 8(a-b) lead to the 1,3-diphosphaallene 4 by action the methyllithium.The anionic ring opening mechanism appears most likely.

FUNCTIONAL PHOSPHINOMETHYL DERIVATIVES: SOME PARALLELS BETWEEN ORGANOPHOSPHORUS AND CARBON CHEMISTRY

The reactivity of P and C in saturated and unsaturated C-P linked organophosphorus species is compared.Novel type main group element phosphine complexes and 1.3 diphospha-allyl, -allene and -butadiene compounds are obtained and characterized by NMR spectr

Isolation and Characterisation of the First Stable Diphospha-allene: P,P'-Bis(2,4,6-tri-t-butylphenyl)-1,3-diphospha-allene

The diphospha-allene, P,P'-bis(2,4,6-tri-t-butylphenyl)-1,3-diphospha-allene (3), was isolated and characterised as a stable compound for the first time.
