Theoretical analysis of intramolecular double-hydrogen transfer in bridged-ring compounds

Journal of Molecular Structure, 1993
Abstract Model calculations are reported on double-hydrogen and double-deuterium transfer rates in two bridged-ring molecules recently investigated by Mackenzie. [Tetrahedron Letters, 33 (1992) 5629]. The calculations indicate that, contrary to an earlier interpretation, the two atoms are transferred by asynchronous tunnelling, the observed ...

¹³C nuclear magnetic resonance spectra of bridged‐ring steroids and related compounds

Magnetic Resonance in Chemistry, 1985
AbstractAssignments of the 13C NMR signals of a series of bridged‐ring steroids incorporating a bicyclo [2.2.1] heptane system into ring A or B have been made on the basis of comparisons of their spectra with those of related unbridged steroids and bicyclo[2.2.1] heptane derivatives.
