应用

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.
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.
Furan derivatives by Pd-catalyzed reaction with acylchromates.
