Dichloro phosphane

The bis(silylation) of alkyldichlorophosphanes and dialkylamino(dichloro)phosphanes, however, with two equivalents of hexachlorodisilane, leading to bis(trichlorosilyl)phosphanes, requires rather... 

The interaction of antimony(III) fluoride with dichloro(phenyl)phosphane leads to oxidative fluorination of the phosphorus atom with the formation of tetrafluoro(phenyl)-/5-phosphane and partial reduction of antimony(III) fluoride to antimony.43... 

Alkyldichlorophosphanes are converted by antimony(III) fluoride into alkyltetrafluoro-A5-phosphanes (RPF4, where R is Me,45,49 Et,45,49 i-Pr,50 allyl,49 Bu45) in 60-80% yield. With electron-withdrawing substituents at the phosphorus atom, e.g. in dichloro(pcntafluoro-phenyl)phosphane, dichloro(chloromethyl)phosphane, dichloro(trichloromethyl)phosphane, diiodo(trifluoromethyl)phosphane or with alkoxy or dialkylamino groups in ROPCl2,... 

Dichloro(trifluorovinyl)phosphane and chlorobis(trifluorovinyl)phosphane react with anti-mony(V) fluoride at room temperature undergoing not only substitution of chlorine but also addition of two fluorine atoms to the phosphorus to give tetrafluoro(trifluorovinyl)-A5-phos-phane and trifluorobis(trifluorovinyl)-A5-phosphane, respectively.100...

Dichloro-(/-butyl)-phosphane and bromomagnesium 4-methylbenzenetellurolate yielded an aryllelluro-substituted diphosphane7. 

Highly strained bicyclic 2-aza-l-phosphiranes 211 and 213 were prepared as Fe/P-clusters by the reaction of Na2Fe(CO)4-l,5-dioxane (Collman s reagent) with corresponding dichloro(dialkylamino)phosphanes 210 and 212 in Et20 at — 30 °C. X-Ray studies demonstrated that saturated bicyclic complex 211 was remarkably stable <2005CEJ3631, 2005JOC8110>. 

Treatment of a solution of bromotrilluoromethane and chloiotriethylgcrmane in dichloro-methane with tris(dicthylamino)phosphane at — 60 C and heating the mixture to 20-22 C leads to formation of triethyl(trifluoromclhyl)germane (52-66% bp 147 C) and the corresponding phosphonium salt. ... 

The reaction of a lithiated organo-fluorine compound with a substituted chlorophosphane leads to the formation of a new C —P bond. In this manner, the phosphorus heterocycle 2 can be obtained from 1,2-diiodotetrafluorocyclobutcne (1) using methyllithium and dichloro-(phenyl)phosphane. ...

BuLi (45 mL of a hexane soln, 90 mmol) in anhyd hexane (25 niL) was added dropwise to a stirred solution of 5 (13.3 g. 44.6 mmol) in THF (150mL, freshly distilled from LiAIH4) at — 75 C. After 3 h, a solution of dichloro(phenyl)phosphane (8.0 g, 44.7 mmol) in THF (15mL) was added dropwise and the mixture was allowed to warm to rt over 2 h. Dil H2S04 was added and the yellow organic layer was separated and dried (CaCl2). Removal of the solvent resulted in a yellow oil. This was transferred to an alumina column and then eluted (petroleum ether bp 40-60 C) a yellow band moved down the column. Removal of the solvent from the eluant and sublimation of the residue at 130 C/10 2 Torr gave 4 as a white solid and left a black intractable tar yield of 4 11.2 g (62%). 

The regiospecific (3 -t- 2) cycloaddition of the bis(diazomethyl)phosphane (236) with (-butylphos-phaalkyne gives the phosphine (237), substituted by 1,2,4-diazaphosphole units. With dichloro-phenylphosphine (237) condenses smoothly to furnish compound (238), with a 1,3,2,5-diazadiphosphinine unit. An analogous condensation with SiCU results in the spiro-linked silicon heterocycle (239) with a 1,3,5,2-diazaphosphasilabenzene structural unit (Scheme 50) <88TL925>. 

Slugovc et al. [31] described the activity of a cis-dichloro catalyst 48 bearing a chelating phosphane ligand (Figure 12.11). This catalyst was slightly air-sensitive... 

Streubel reported the synthesis of phosphinite complexes 107, via reaction of transient Li/Cl phosphinidenoid complexes, prepared from dichloro(organo)phosphane complexes with different alcohols. NMR studies on deprotonation reactions of P-CgMcs- and P-CPhs-substituted methojyphosphinite complexes provided new insights into formation and stability of Li/OMe phosphinidenoid complexes.
