(E)-Cinnamonitrile is an organic compound approved for use as a fragrance in products such as air fresheners.[2][3] It has a spicy cinnamon aroma.

Synthetic routes include an aldol-like condensation of benzaldehyde with acetonitrile under alkaline conditions,[4] an elimination reaction of various oximes derived from cinnamaldehyde,[5] and oxidative coupling of benzene to acrylonitrile.[6]
