Photochemical reactions of triplet phenylphosphinidene with carbon monoxide and nitric oxide

Here we report the photochemical reactions of triplet phenylphosphinidene with carbon monoxide and nitric oxide. The photolysis of phenylphosphirane in carbon monoxide-doped matrices enabled the first spectroscopic identification of phenylphosphaketene, t

A new stereoselective synthesis of phosphiranes

The synthesis of phosphiranes from primary phosphines and diol ditosylates was found to be stereoselective, and chiral phosphiranes were prepared from optically pure diols. The four optical isomers of 1-mesityl-2,3-dimethylphosphirane, (2S,3S)-(+)-3, (2R,3R)-(-)-4, anti-cis-(meso)-5, and syn-cis-(meso)-6, were all synthesized from mesitylphosphine and the corresponding diol ditosylates. Compound 6 was unstable, but compounds 3, 4, and 5 were all isolated in pure form. Their structure assignments were based on the NMR coupling constants JP-H and JP-C. The phosphiranes were transformed into tungsten pentacarbonyl complexes. Tungsten tetracarbonyl-triphenylphosphine complexes (22, 23, 24) of compounds 3, 4, and 5 were synthesized in high yields by the reaction of the phosphiranes and W(CO)4(PPh3)(THF). The absolute stereochemistry of the phosphiranes 3, 4, and 5 was determined by X-ray crystal structure analysis of compounds 22, 23, and 24. Stereochemical effects on NMR coupling constants and mass spectra of the phosphiranes are discussed.

Preparation and Characterization of Parent Phenylphosphinidene and Its Oxidation to Phenyldioxophosphorane: The Elusive Phosphorus Analogue of Nitrobenzene

Triplet phenylphosphinidene was prepared by light-induced elimination of ethylene from the corresponding phenylphosphirane and was characterized by IR and UV/vis spectroscopy together with matching of its spectral data with density functional theory computations. The photolysis of phenylphosphirane in 3P-O2 doped matrices enabled the spectroscopic identification of a hitherto unknown phenyldioxophosphorane, the long elusive phosphorus analogue of nitrobenzene.

Dilithium phenylphosphide reacts with 1,3-dichloropropane or 1,2-dichloroethane to give 1-phenylphosphetane or 1-phenylphosphirane, respectively; the free phosphines have been used to prepare the cyclotrimerisation precursor complexes and formu

METALLA IV-b-PHOSPHOLANNES II-METALLA-2 (OXA-, THIA- ou AZA-)-3 PHOSPHOLANNES

2-sila-, germa- or stanna- 3-(oxa-, thia- or aza-) phospholanes have been synthesized by reactions of dihalometalla-IV-b compounds with dilithiated β-phosphorus alcohols, thiols or amines HYCH2CH2P(H)Ph (Y=O, S, NMe).Germa- and stanna- heterocycles can also be obtained from germyl- or stannyldiamines and the same β-phosphorus alcohols, thiols or amines. 2-sila 3-(oxa- or thia-) phospholanes are of particular interest for their decomposition reaction leading to silanone or silathione and phosphirane.
