We compute the decay rates for the exclusive decays B± → (η′,η) (K±, K*±) and B0→ (η′,η) (K0, K*0) in a QCD-improved factorization framework by including the contribution from the process b→ sgg → s (η′, η) through the QCD anomaly. This method provides an alternative estimate of the contribution b → s cc → s(η,η^′) to these decays as compared to the one using the intrinsic charm content of the η′ and η mesons determined through the decays J/ψ→ (η,η^′ ,ηc) γ. The resulting branching ratios are compared with the CLEO data on B± → η′ K± and B0 → η′ K0 and predictions are made for the rest.
