Preparation of 3-phenylpropiolonitrile
Alternative Names: Phenylpropiolonitrile; 2-Propynenitrile, 3-phenyl-; 3-phenyl-2-propynenitrile; Cyanophenylacetylene;
A mixture of 1 equiv. of 3-phenylprop-2-ynal (phenylpropiolaldehyde) and 1.1 equiv. of hydroxylamine hydrochloride are mixed with the dimethylsulfoxide until the homogeneous mixture is obtained (3-5 volumes) and the obtained mixture is stirred at 70° C for 1-2 hours. The reaction is monitored by TLC (ethyl acetate:hexane 5:95) and when is completed the mixture is cooled and poured in water, the reaction product is extracted with ether, dried and the ether is removed by evaporation affording 93% of the 3-phenylpropiolonitrile.
