oa South African Journal of Chemistry - Hydrogen bonding patterns in a series of 3-spirocyclic oxindoles : research article

Volume 63, Issue 1
  • ISSN : 0379-4350



The crystal structures of the new compounds spiro[cyclohexane-1,3'-indol]-2'(1')-one (), (-1,2)-spiro[bicyclo[2.2.1] heptane-2,3'-indol]-2'(1')-one () and spiro[indole-3,2'-tricyclo[,7]decan]-2(1)-one () have been determined by low temperature single crystal X-ray diffraction. The effects of substitution on the hydrogen bonding pattern is compared between all three compounds.
