2-azulenediones) (la–c) were synthesized by dehydrogenation of the corresponding 1,2-dihydroxyazulenes (5a–c) which were prepared from 2-acetoxyazulenes (2b,c) by benzoyloxylation followed by hydrolysis. Some chemical and physical properties of la–c are also described.
                                    1,2-Azulenequinones (1,2-azulenediones) (la–c) 是通过相应的 1,2-dihydroxyazulenes (5a–c) 脱氢合成的
