摘要：

Fluorene‐9‐13C, fluorenone‐9‐13C, acenaphthenone‐11‐13C, acenaphthenone‐12‐13C, 1‐methylcyclopentanol‐1‐13C and 1‐methylcyclopentene‐1‐13C were synthesized to obtain J(CC) values between the natural carbons and the labeled carbons. Each of these compounds possessed at least one asymmetric dual‐path coupling, i.e., coupling between the labeled carbon and another carbon via simultaneous two‐ and three‐bonded coupling paths. Model 13C‐labeled compounds were synthesized where necessary to give expected values of the constituent mono‐path couplings. Values of these dual‐path couplings (2+3)J suggested that the observed value is the (at least approximate) algebraic sum of the two constituent J values. Copyright © 1979 Heyden & Son Ltd.
