Description

Application

Propargyl p-toluenesulfonate can be used as an initiator in the synthesis of linear and cyclic poly(2-isopropyl-2-oxazoline)s by cationic ring-opening polymerization of 2-isopropyl-2-oxazoline.[1]
It can also be used as a reagent to synthesize:

• 2-hydroxy-4-pentynoic acid by an alkylation reaction with diethyl 2-acetamidomalonate followed by subsequent hydrolysis, decarboxylation, diazotization, and hydroxylation reactions.[2]
• Furan derivatives by Pd-catalyzed reaction with acylchromates.[3]
