OXALYL CHLORIDE REAGENTPLUS >=99% (C005B-081042)

General description

Oxalyl chloride is a commonly used chlorinating reagent that can be prepared by the reaction of oxalic acid and phosphorus pentachloride.

Application

Oxalyl chloride may be used in the following processes:

• Preparation of Mosher′s acid chloride by reacting with Mosher′s acid in the presence of DMF.
• Activation of dimethyl sulfoxide for use in the oxidation of long-chain alcohols to carbonyls.
• Activation of α-keto carboxylic acids and N-heterocyclic carboxylic acids for alkynylation to form ynediones and N-heterocyclic ynones, respectively.

Suitable for the synthesis of acid chlorides used to produce liquid crystals.

Reactant involved in:

• Synthesis of N-heterocyclic ynones and ynediones, used to activate carboxylic acids
• Chlorination and halogenation
• Three-component [3+2] cycloadditions
• Reactions with organostannanes
• Synthesis of cyclopentenones
• Carbonylations, used as a carbonyl synthon

Packaging

The 5g, 25g and 100g units sold in the US are packaged in ampules.
