TOC Text: The Diels‐Alder reaction of β‐fluoro‐β nitrostyrenes with some linear dienes is reported. The kinetic studies were carried out to reveal substituent effect and activation parameters of the reaction. A new family of monofluorinated cyclohexenes 2 was prepared. The further transformation of 2 into biphenyls 3 based on base‐induced elimination of HNO2 followed by oxidative aromatization were
