Tributylphosphane Usage And Synthesis
Chemical Properties Clear liquid
Usage 1,4-addition catalyst; used with disulfides for the thioetherification of alcohols; acylation catalyst; used to prepare active esters.
Usage suzuki reaction
General Description Tributylphosphane is a colorless to yellowish liquid with a strong garlic-like odor. Tributylphosphane is insoluble in water. Tributylphosphane is liable to heat and ignite spontaneously in air. If involved in a fire phosphine gas, a highly flammable and toxic gas, will evolve. Tributylphosphane is irritating to mucous membranes.
Air & Water Reactions Highly flammable. May ignite on contact with air or moist air. Insoluble in water.
Reactivity Profile Organophosphates, such as Tributylphosphane, are susceptible to formation of highly toxic and flammable phosphine gas in the presence of strong reducing agents such as hydrides. Partial oxidation by oxidizing agents may result in the release of toxic phosphorus oxides.
Health Hazard Fire will produce irritating, corrosive and/or toxic gases. Inhalation of decomposition products may cause severe injury or death. Contact with substance may cause severe burns to skin and eyes. Runoff from fire control may cause pollution.
Fire Hazard Flammable/combustible material. May ignite on contact with moist air or moisture. May burn rapidly with flare-burning effect. Some react vigorously or explosively on contact with water. Some may decompose explosively when heated or involved in a fire. May re-ignite after fire is extinguished. Runoff may create fire or explosion hazard. Containers may explode when heated.
