Opis

Application

Catalyst for:
Synthesis of primary amides
Direct dehydrative phosphonium cross coupling
Direct arylation
Pyrrolidide formation by phosphonium salt coupling reagents

It can be used as a coupling reagent:

• For Suzuki–Miyaura cross-coupling of phenols and arylboronic acids to synthesize biaryls and heterobiaryls.
• To functionalize pyrimidines (synthesized from 3,4-dihydropyrimidin-2(1H)-ones (DHPMs) via the Kappe dehydrogenation) by using various nucleophiles.
• To synthesize formamidines by coupling with various primary amines and N,N-diisopropylethylamine.

It can also be used as an activating reagent:

• For the activation of C-OH bond in tautomerizable heterocycles to form the phosphonium salt which aids the Sonogashira coupling of heterocycles with various alkynes.
• For the one–pot activation of C-O bond in phenols and further coupling reaction with phosphine oxide or phosphite to form C-P bonds.
