Pyridazines were reacted with allyltributyltin in the presence of chloroformate to give 1-alkoxycarbonyl-6-allyl and 1-alkoxycarbonyl-4-allyldihydropyridazines as major and minor products, respectively. The reaction system was applied to other diazines and pyrimidine and pyrazine were shown to afford diallytetrahydroadducts. Benzodiazines also gave allylation products in good yields. The reaction seems to be applicable to most six-membered azaaromatics.
