Product is the 70wt. % solution of propargyl chloride in toluene. Propargyl chloride is a propargyl halide. Its trimethylsilylation reaction has been reported. Liquid-phase Raman spectra, and vapor-phase and solution-phase infrared spectra of propargyl chloride has been studied at 100-3400cm-1 and 300-3800cm-1, respectively. It participates in the addition reaction with acyclic 1,3-dienes (at -78°C) in the presence of zinc chloride.
