Description

Reagent used in organic synthesis. Unncatalyzed reaction of silyl ketene acetals with oxalyl chloride yeilds symmetrical pulvinic acids. Catalytic syntheses of N-heterocyclic ynones and ynediones by in situ activation of carboxylic acids with oxalyl chloride. Oxalyl chloride was reportedly used in the first synthesis of dioxane tetraketone.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
