我们对利用ESR光谱研究脂环自由基的构象效应很感兴趣，现在希望报告我们对桥头堡十氢化氢自由基的研究结果。通过光解同分异构体桥头堡铁-丁氧基酯来获得这些叔自由基的明显方法是不成功的。从纯顺式和fra/w-十氢化萘中提取氢原子，光解生成的re/7-丁氧自由基产生所需的桥头堡自由基，我们通过esr光谱观察到。光谱分析表明，自由基是非平面的，可区分的。
We are interested in studying conformational effects in alicyclic radicals by means of ESR spectroscopy1" 3 and now wish to report our results on the bridgehead decalin radicals. The obvious approach4 to these tertiary radicals, by photolysis of the isomeric bridgehead ferf-butoxy peresters, was unsuccessful. 5 Hydrogen atom abstraction from pure cis-and fra/w-decalin with photo-lytically generated re/7-butoxy radicals yielded the desired bridgehead radicals, which we observed byESR spectroscopy. Analyses of these spectra suggest that the radicals are nonplanar and distinguishable.
