(2) CH3CN3的100-MHz 1H NMR显示氘同时位于Ci和C4。然而，C4和C3质子的低标记量和部分重叠妨碍了每个碳上的严格分配。(3)关于III环质子的核磁共振分配见A. Mannschreck和U. Kolle, Chem。方方面面。， 102, 243（1969）。
(2) By 100-MHz 1H NMR in CH3CN3 deuterium appeared to be both at Ci and C4. However, the low amount of label and partial overlap of the C4 and C3 protons precluded rigorous assignment of amounts at each carbon.(3) For NMR assignment of the ring protons of III see A. Mannschreck and U. Kolle, Chem. Ber., 102, 243 (1969).
