Description

General description

3-Phenyl-1-propyne is a 3-aryl-1-propyne. The electronic transition of the resonance-stabilized 1-phenylpropargyl radical, produced in a jet-cooled discharge of 3-phenyl-1-propyne, has been studied by laser-induced fluorescence excitation and dispersed single vibronic level fluorescence (SVLF) spectroscopy. The microwave rotational spectrum of 3-phenyl-1-propyne (propargyl benzene) has been studied and its stable conformation is reported to have coplanar carbon atoms. Reaction of N-methyl-N-phenylhydrazine or N-phenylhydrazine with 3-phenyl-1-propyne is reported to yield indoles. 3-Phenyl-1-propyne is reported to react with styrene oxide and sodium azide, to afford β-hydroxytriazoles.

Application

3-Phenyl-1-propyne may be used as starting reagent in the synthesis of 4-phenyl-2-butyn-1-ol.
