General description

Propargyl chloride is an efficient propargylating agent. It generates propargyl radicals by the pulsed laser photolysis.

Application

Propargyl chloride was used to study emission spectra of dissociating propargyl chloride upon photoexcitation at 199 nm. It was used in the synthesis of novel tetraaryl analog of bisphenol A and triaryl analog of bisphenol A propargyl resins.
