Loss, Sandra,Widauer, Christoph,Rueegger, Heinz,Fleischer, Ulrich,Marchand, Christina M.,Gruetzmacher, Hansjoerg,Frenking, Gernot
, p. 85 - 91 (2007/10/03)
Isomeric bis(phosphanyl) carbenium ions have been investigated by theoretical [MP2/6-31G(d,p) level of theory] and experimental means. On the potential energy surface (PES) of phosphorus cations of the formula [P 2CH5]+, f
Isolation of a Highly Persistent Diphosphanyl Radical: The Phosphorus Analogue of a Hydrazyl
Loss, Sandra,Magistrato, Alessandra,Cataldo, Laurent,Hoffmann, Stefan,Geoffroy, Michel,Roethlisberger, Ursula,Gruetzmacher, Hansjoerg

Stable for at least one week below -30°C: crystals of 1, the first highly persistent diphosphanyl radical, have been isolated and characterized. This phosphorus-centered radical exhibits hyperfine coupling whose anisotropy is considerably larger than that for well-established nitrogen radicals (hydrazyls nitroxides). This feature is of potential interest for studies of fast molecular movements. Mes =2,4,6-tBu3C6H2.
Strong P=P π bonds: The first synthesis of a stable phosphanyl phosphenium ion
Loss, Sandra,Widauer, Christoph,Gruetzmacher, Hansjoerg
, p. 3329 - 3331 (2007/10/03)
A 35-fold excess of methyl triflate (2) is required to quantitively prepare 3, the first phosphanyl phosphenium ion, from diphosphene 1. Experimental data and calculations indicate that the P=P bond becomes stronger upon alkylation.
Sonochemistry in the diphosphirane series
Etemad-Moghadam,Rifqui,Layrolle,Berlan,Koenig
, p. 5965 - 5968 (2007/10/02)
Sonication improves substantially the rate of formation of diphosphene 1 with respect to standard procedures. The cyclopropanation of 1 using sonochemical generation of methylene or halogeno-carbenes constitutes an interesting alternative in the diphosphi

A GENERAL METHOD FOR PREPARING DIPHOSPHIRANES
Etemad-Moghadam, Guita,Bellan, Jacques,Tachon, Christine,Koenig, Max
, p. 1793 - 1798 (2007/10/02)
Diphosphiranes 3a-3f are obtained by action of diazo derivatives and carbenes on the trans-diphosphene 1.The structures are elucidated by spectroscopic methods.In all cases the cycloaddition reaction is stereoselective.
REACTIVITY OF DIPHOSPHENE TOWARDS OXYGEN AND DIAZO DERIVATIVES: NEW METHOD OF OBTAINING STABLE DIPHOSPHIRANES
Koenig, Max,Etemad-Moghadam, Guita,Tachon, Christine,Bellan, Jacques
, p. 425 - 428 (2007/10/02)
Different aspects of the reactivity of the diphosphene are presented : reactivity of the lone pair and/or reactivity of the double bound.
