Abstract
8-Aryl-1-(1H-benzo[d][1,2,3]triazole-yl)-4,4-difluoro-4-bora-3a,4a-diaza-s-indacene and 8-aryl-3,5-di-(1H-benzo[d][1,2,3]triazole-yl)-4,4-difluoro-4-bora-3a,4a-diaza-s-indacene derivatives were synthesised by the reaction of 4,4-difluoro-4-bora-3a,4a-diaza-s-indacene with benzo[d][1,2,3]triazole in the presence of Selectfluor in moderate to good yields. The reaction took placed regioselectively on the 3(5)-position carbon of 4,4-difluoro-4-bora-3a,4a-diaza-s-indacene, which was confirmed by X-ray analysis.
