Applicazioni

Polymer-bound triphenylphosphine is a solid-supported reagent that can be used as a better alternative to triphenylphosphine in the Mitsunobu reaction.
It can also be used:
  • For the esterification of alkylphosphonic acids using primary alcohols in the presence of iodine and imidazole.
  • To catalyze the conversion of 3-[3-(1,3-dioxolan-2-yl)-1-hydroxypropyl]pyridine to 3-[1-bromo-3-(1,3-dioxolan-2-yl)propyl]pyridine using carbon tetrabromide.
  • To isomerize (Z)-nitro olefins to the (E)-isomers.
  • To prepare polymer-bound ylides which are useful in Wittig reactions.
  • To convert alcohols or carboxylic acids to the corresponding chlorides.
  • In combination with carbon tetrachloride for the coupling N-alkoxycarbonyl α-amino acids and primary amines to form the corresponding amides.

Altre note

Polymer-bound triphenylphosphine is used for preparing polymer-bound yields which are highly useful for Wittig reactions; removal of the polymer at the end of the reaction removes all the phosphine oxide.
