Previous studies of interstellar chemistry based on the standard model of Brown et al. (1990) are extended and updated, with particular emphasis on the effect of adding ion-atomic oxygen reactions and also neutral-neutral atomic oxygen reactions. The formation of the series CnO and H2CnO up to n = 5 is included, and the formation of the cyclic molecule H3C4NO is investigated. The effect of adding ion-atomic oxygen reactions to the present model is negligible. If the neutral-atomic oxygen reactions proceed efficiently in dark clouds, there is a substantial curtailment of production of complex species, even at early times, where agreement is best in such models. It is concluded that, if neutral-atomic oxygen reactions proceed efficiently, the production of complex species in observable amounts in dark clouds is not possible unless the addition of further radiative associations is found to be important in the formation of complex species. If the neutral-atomic oxygen reactions do not proceed efficiently, the species CnO and H2CnO up to n = 5 should at least be observable in dark clouds.
