Descrição

Aplicação

Sodium sulfate can be used as a catalyst:

• In the Suzuki-Miyaura cross-coupling reactions of aryl halides with arylboronic acids to synthesize biaryl compounds in the presence of PdCl₂.
• For the aminolytic depolymerization of PET (polyethylene terephthalate) bottle waste.

It can also be used as an additive in the Pd-catalyzed Sonogashira reaction of terminal alkynes with aryl halides to synthesize polyfunctional alkynes.
