    8 Pfau and Plattner were able to validate their proposal through the synthesis of a blue hydrocarbon which possessed the azulene nucleus, see: Pfau, P.; Plattner, P1.

    methods for the synthesis of azulenes have relied heavily on a dehydrogenative approach in which a suitable hydroazuleneprecursor is oxidized to the fully aromatic product. In fact, the landmark 1936 synthesis of 4-methylazulene (22) by Pfau and Plattner used this strategy (eq 1).
