Synthesis of 2-aryl-6-(4-bromophenyl)-4-(2,2-dichlorovinyl)pyridines with the use of 1-aryl-5,5-dichloropenta-2,4-dien-1-ones
摘要:
Heating 1-aryl-5,5-dichloropenra-2,4-dien-1-ones with 4-bromophenacylpyridinium bromide in AcOH in the presence of AcONH4 gave 2-aryl-6-(4-bromophenyl)-4-(2,2-dichlorovinyl)pyridines. The reaction products we re structurally characterized by H-1 and C-13 NMR spectroscopy.
