The amplitudes for processes like B → Dπ− and B → D∗π− are dominated by factorizable contributions wh relate these amplitudes to the semileptonic form factors in B → Deve and B → D∗eve. Factorization, together w heavy quark symmetry, leads to absolute predictions for ratios of decay rates. For example, Γ(B → Dπ−)Γ(B → D∗π−) = 1. We calculate perturbative strong interaction corrections to factorization and discuss their influence on the ration of decay rates Γ(B → Dπ−)/Γ(B → D∗π−). The decays B → Dϱ− and B → D∗ϱ− are also discussed.
