naphthalenes with isopropyl, 2‐hydroxy‐2‐methylethyl and 2‐hydroperoxy‐2‐methylethyl substituents by the use of proton–proton decoupling, 2D H,H‐COSY and 2D‐C,H‐COSY techniques. The downhill simplex method was used for calculations of the best set of 13C and 1H incremental shifts. An excellent additivity of substituent effects was found for both, the 13C and 1H spectra of 2,6‐disubstituted naphthalenes. Copyright
通过使用质子 - 质子去耦,2D 对三个具有异丙基、2-羟基-2-甲基乙基和 2-氢过氧-2-甲基乙基取代基的 2-取代和 6 个 2,6-二取代萘进行了 13C 和 1H 光谱分配H,H-COSY 和 2D-C,H-COSY 技术。下坡单纯形法用于计算 13C 和 1H 增量偏移的最佳集合。对于 2,6-二取代萘的 13C 和 1H 光谱,均发现了优异的取代基效应的可加性。版权所有 © 2000 John Wiley & Sons, Ltd.
