摘要

The presence of the alicyclic ring in indan has been shown by a physical method to cause no significant bond fixation of the type proposed by Mills and Nixon. This conclusion results from infrared observations of the reduction in the C= O vibrational frequency arising from conjugated chelation of adjacent hydroxyl and carbonyl-containing groups. These frequency shifts, Av (C= O), were found previously to be directly proportional to thc double-bond ...
