Abstract

Reaction of 2-chloro-1-azaazulenes with phenylmagnesium bromide gave addition-type products, and dehydrogenation thereof afforded 4-, 6-, and 8-phenyl-2-chloro-1-azaazulenes. It is concluded from product yields that the reactivity of the ring position of the 2-chloro-l- azaazulene system towards this reagent increases in the order of C(8)»C(4)>C(6).
