Triphenylphosphine, polymer-supported, 1.4-2.0 mmol/g on polystyrene

MDL
MFCD00148025

Proprietà chimiche

Applicazioni

Triphenylphosphine is used as a support for nickel, rhenium and rhodium in hydrogenation, in dimerization of alkenes and in hydroformylation. It is also used for the halogenation of carboxylic acid and alkanes in carbon tetrachloride, addition of iodine in DMF esterifies primary and secondary alcohols to their respective formate esters and in the Mitsunobu and the Wittig reactions.

Note

Store in cool place. Keep container tightly closed in a dry and well-ventilated place. Incompatible with oxidizing agents.
