Descripción

Application

2,6-Difluorobenzaldehyde can be used as a reactant to synthesize:

• 5-Cyano-6-(2,6-difluorophenyl)-5,6-dihydro-2-thiouracil via one-pot cyclocondensation reaction with ethyl cyanoacetate and thiourea.
• 1-(2,6-Difluorobenzyl)-2-(2,6-difluorophenyl)-benzimidazole by reacting with 1,2-phenylenediamine in the presence of a catalytic amount of p-toluenesulfonic acid.
• (3E)-4-(2,6-Difluorophenyl)-3-buten-2-one by Wittig olefination reaction with acetylmethylidenetriphenyl phosphorane.
• Methyl 4-fluorobenzo[b]thiophene-2-carboxylate by treating with methyl thioglycolate in the presence of K₂CO₃.
