WebTributylphosphine, [1] formula P (C 4 H 9) 3 or PBu 3, is a tertiary phosphine, most commonly encountered as a ligand in transition metal complexes. It its an oily liquid at … WebTributylphosphine was found to be an effective promoting reagent for ring opening of a variety of aziridines and nucleophiles to produce anti-bifunctional products in good to excellent yield. The study showed that the reaction is initiated through the attack of tributylphosphine as a nucleophile at the carbon atom of the aziridine ring.

Tributylphosphine is the organophosphorus compound with the formula P(C 4H 9) 3. Abbreviated or PBu 3, it is a tertiary phosphine. It is an oily liquid at room temperature, with a nauseating odor. It reacts slowly with atmospheric oxygen, and rapidly with other oxidizing agents, to give the corresponding phosphine … See more Tributylphosphine is prepared industrially by the hydrophosphination of phosphine with butene: the addition proceeds by a free radical mechanism, and so the Markovnikov rule is not followed. PH 3 + 3CH 2=CHCH … See more The main laboratory inconvenience of tributylphosphine is its unpleasant smell. See more Tributylphosphine is moderately toxic, with an LD50 of 750 mg/kg (oral, rats). See more Tributylphosphine reacts with oxygen to give the phosphine oxide: 2 PBu3 + O2 → 2 OPBu3 Because this reaction is so fast, the compound is usually … See more Tributylphosphine finds some industrial use as a catalyst modifier in the cobalt-catalyzed hydroformylation of alkenes, where it greatly increases the ratio of straight-chain aldehydes to branched-chain aldehydes in the product mixture.
