(i) the carbon para to the variable substituent X is more sensitive to change of substituent in the naphthalenes than in the benzenes, (ii) of the carbons ortho to the variable substituent X, that at C‐3 is more sensitive and that at C‐4a is less sensitive, to change of substituent in the naphthalenes than in the benzenes, (iii) the effect of the 4‐substituents on the shift of H‐8 in 1‐acetylnaphthalenes
10 种 4-X-l-乙酰萘的质子和碳光谱已被指定。已经以苯取代基诱导的化学位移(SCS,Lynch 图)和双取代基参数(DSP)建立了位移相关性,这对于许多系列的 1,4-二取代苯已经成功完成。将所得结果与 4-X-苯乙酮和 1-X-萘的结果进行比较。主要结论是 (i) 可变取代基 X 的碳对位对萘中取代基的变化比苯更敏感,(ii) 可变取代基 X 邻位的碳,在 C-3 处更敏感敏感并且在 C-4a 对萘中取代基的变化比苯中的变化不那么敏感,
