実験手順
A solution of 2-(2,6-dichloro-4-trifluoromethylphenyl)-2H-1,2,3-triazole-4-carboxaldehyde (3.1 g), in dichloromethane (20 ml) was added to a solution of triphenylphosphonium dibromide at -20° (prepared by mixing a solution of carbon tetrabromide (31.2 g) in dichloromethane (30 ml) with a solution of triphenylphosphine (21 g) in dichloromethane (70 ml)) and the mixture stirred for 1 hour. Hexane was added and the mixture filtered. The filtrate was worked up to give 2-(2,6-dichloro-4-trifluoromethylphenyl)-4-(2,2-dibromo-vinyl)-2H-1,2,3-triazole. 89°-91° . (Compound 24)
