Peri interaction in several naphthalene ketones was investigated using the carbon-13 NMR, IR, and UV spectra. The carbonyl carbon resonances for 7H, 14H-cycloocta[1,2,3-de:5,6,7-d′e′]dinaphthalene-7,14-dione and its 7-oxa analog were found to be shifted upfield by 27 and 24 ppm respectively compared with those of model compounds. The anomalous shift for the former was attributed to π-orbital compression
使用碳 13 NMR、IR 和 UV 光谱研究了几种萘酮中的 Peri 相互作用。发现 7H, 14H-cycloocta[1,2,3-de:5,6,7-d'e']dinaphthalene-7,14-dione 及其 7-oxa 类似物的羰基碳共振通过与模型化合物相比,分别为 27 和 24 ppm。前者的异常位移归因于 π 轨道压缩,由于强制平行几何结构抑制了羰基的极化,而后者归因于场效应。该结论得到了紫外和红外数据的支持。
