Reaction of IC1 with chalcones yielded 2-iodo-3-chloro-1,3-diphenylpropanones-(1) (II), which were identified by their 1H-NMR spectra as erythro isomers. The IR spectra of the II were compared with the IR spectra of the 2,3-dibromo compounds (I) in the range of 400 to 700 cm−1 and in the carbonyl frequency region.
IC1与查耳酮反应生成2-碘-3-氯-1,3-二苯基丙烷-(1)(II),通过其1 H-NMR光谱确定为赤型异构体。将II的IR光谱与2,3-二溴化合物(I)的IR光谱在400至700cm -1的范围内以及在羰基频率范围内进行比较。
