Usage

General Description

Methylphosphin, also known as trimethylphosphine, is a colorless, flammable gas with a pungent odor. It is highly toxic and can cause irritation to the respiratory system and skin upon contact. Methylphosphin is primarily used as a chemical intermediate in the production of agricultural chemicals, pharmaceuticals, and flame retardants. It is also used as a catalyst in various chemical reactions and as a reagent in organic synthesis. Due to its toxic and flammable nature, methylphosphin should be handled with caution and appropriate safety measures.

Gas-Phase Chemistry of H2P(-)

The gas-phase ion-molecule chemistry of H2P(-) has been investigated by using the flowing afterglow technique.Generated by proton abstraction from PH3 by H2N(-) or OH(-), H2P(-) reacts with N2O, CO2, OCS, CS2, O2, NO2, SO2, CH3X, and (CH3)3SiCl to yield a variety of ion products.Products usually arise from initial nucleophilic attack of H2P(-) on the neutral, followed by intramolecular proton transfer and/or expulsion of a neutral fragment.Many of the reactions are similar to those for H2N(-), though differences are attributable to the weaker nucleophilicity of H2P(-).Product branching ratios and reaction rate constants are reported, and possible mechanistic pathways are discussed.

Synthesis, photoelectron spectroscopy and quantum chemical study of kinetically unstabilized phosphines complexed by borane

Ethynyl- and allenylphosphine-boranes have been prepared by addition at low temperature of borane on the free phosphine. Purification was performed by selective trapping in vacuo and the complexes were characterized by NMR and infrared spectroscopy and ma

B(C6F5)3-catalyzed silylation versus reduction of phosphonic and phosphinic esters with hydrosilanes

HSiR3/cat-B(C6F)3 induced dealkylation or reduction of esters of phosphorus at 20°C. A specific conversion to silylesters occurred by reaction with tertiary silanes. In contrast, free phosphines were observed in the reaction with mono- or disubstituted silanes. A mechanism was proposed to rationalize these results.
