General description

Propargyl chloride is an efficient propargylating agent[1]. It generates propargyl radicals by the pulsed laser photolysis[2].

Application

Propargyl chloride was used to study emission spectra of dissociating propargyl chloride upon photoexcitation at 199 nm[3]. It was used in the synthesis of novel tetraaryl analog of bisphenol A and triaryl analog of bisphenol A propargyl resins[4].
