摘要：

The mass spectra of bicyclic ketones bicyclo[4.2.1]nonan‐9‐one, bicyclo[5.2.1]decan‐10‐one, bicyclo[4.3.1]decan‐10‐one and bicyclo[5.3.1]undecan‐11‐one specifically deuterated in positions both adjacent and nonadjacent to the carbonyl carbon have been investigated. The fragmentation and rearrangement processes predominating appear to be dictated by the inherent strain in the molecules. An unusual tendency for fragment ions to recyclize is supported by deuterium labeling results, high resolution mass measurements, metastable studies and comparison with model compounds. The mass spectra of the bicyclic ketones under investigation are considerably more complex than those of acyclic ketones. Copyright © 1978 Heyden & Son Ltd
