We consider the hadronic B decays B0→ D0η, B0 → D*0η, B0→ D0η', B0 → D*0η' in the framework of a quark-flavour basis and factorization. The formalism allows one to compute the decays to the η meson and to relate them to those of the η'. Measuring the branching ratios of these processes may shed light on the nature of the η--η' mixing. On the experimental side, only upper limits on the branching ratios are known at present.
