2phenylpropanenitrile

2-Phenylpropanenitrile is an organic compound with the chemical formula C9H9N. It is a derivative of propanenitrile, where one hydrogen atom is replaced by a phenyl group. The compound is a colorless liquid at room temperature, with a boiling point of approximately 200°C. It is soluble in organic solvents such as ethanol and dichloromethane, but insoluble in water.

2-Phenylpropanenitrile is primarily used as an intermediate in the synthesis of various pharmaceuticals and agrochemicals. It can undergo various chemical reactions, including nucleophilic substitution and reduction, to form a wide range of derivatives. For example, it can be reduced to 2-phenylpropanamine, which is a useful building block in the synthesis of certain drugs.

The compound is typically prepared by the reaction of phenylacetone with cyanide ion in the presence of a base. The reaction proceeds via an aldol condensation followed by dehydration and cyanation. The product is then purified by distillation or recrystallization.

2-Phenylpropanenitrile is a flammable liquid and should be handled with care. It is also a potential health hazard, as it can cause skin and eye irritation. Proper personal protective equipment should be worn when handling the compound.
