Reaction of 7-substituted cycloheptatrienes with either hexacarbonylchromium or with tricarbonyltripyridine-chromium leads to the corresponding 7-endo-substituted tricarbonylcycloheptatrienechromiums, either exclusively or, in only two of the cases studied, mixed with the exo-isomer. Some new observations on the ring-contraction of such complexes are reported.
