## Abstract 1β(Bromoacetyl)β3βmethylazulene **(1a)** and methyl 3β(bromoacetyl)azuleneβ1βcarboxylate **(1b)** reacted with thioamides **3a,b** and thioureas **3c,d** in boiling ethanol to give the corresponding (4βthiazolyl)azulenes **4aβd** and **5aβd** in good yields, respectively. The reactions
Azulenes reacted unexpectedly and readily with thionyl chloride to give sulfonic acid chlorides and bisthioethers. The sulfonic acids but not the thioethers have antibacterial activity.
in ethanol 1) +AzH in CH 3 NO 2 2) AcONH 4 (a) (b) 4-Azulen-1-yl substituted 2,6-dimethyl-and 2,6-diphenyl-pyridines are obtained in good yields from the reaction of corresponding 4-azulen-1-yl-pyranylium salts and ammonium acetate in ethanol or starting from 4-chloro-2,6-diphenyl-pyranylium salts
