WebJe viens de terminer un M2 recherche à Toulouse I dans l'objectif de poursuivre par une thèse en droit international privé, matière tout à fait passionnante. Mon parcours s'appuie sur plusieurs piliers : (1) une bonne connaissance de la chimie et du génie des procédés = école d'ingénieurs, thèse (2) une maîtrise du droit des brevets = CEIPI, EQE, … Triphenylphosphine (IUPAC name: triphenylphosphane) is a common organophosphorus compound with the formula P(C6H5)3 and often abbreviated to PPh3 or Ph3P. It is widely used in the synthesis of organic and organometallic compounds. PPh3 exists as relatively air stable, colorless crystals … See more Triphenylphosphine can be prepared in the laboratory by treatment of phosphorus trichloride with phenylmagnesium bromide or phenyllithium. The industrial synthesis involves the reaction between phosphorus trichloride See more Oxidation Triphenylphosphine undergoes slow oxidation by air to give triphenylphosphine oxide, Ph3PO: 2 PPh3 + O2 → 2 OPPh3 This impurity can be removed by recrystallisation of … See more Polymeric analogues of PPh3 are known whereby polystyrene is modified with PPh2 groups at the para position. Such polymers can be employed in many of the applications used for PPh3 with the advantage that the polymer, being insoluble, can be … See more • International Chemical Safety Card 0700 See more PPh3 is widely used in organic synthesis. The properties that guide its usage are its nucleophilicity and its reducing character. The nucleophilicity of PPh3 is indicated by its reactivity toward … See more Triphenylphosphine binds well to most transition metals, especially those in the middle and late transition metals of groups 7–10. In terms of steric bulk, PPh3 has a Tolman cone angle of 145°, which is intermediate between those of P(C6H11)3 (170°) and P(CH3)3 … See more • Tris(o-tolyl)phosphine • Decyl(triphenyl)phosphonium See more thirsty dog holcomb ks
