n-Butylbenzene is the organic compound with the formula C₆H₅C₄H₉. Of two isomers of butylbenzene, n-butylbenzene consists of a phenyl group attached to the 1 position of a butyl group. It is a slightly greasy, colorless liquid.

The synthesis of n-butylbenzene by the reaction of chlorobenzene and butylmagnesium bromide was one of the first demonstrations of the Kumada coupling using nickel diphosphine catalysts.^[1] This mild and efficient process contrasted with older methods.^[2]
