Nonleptonic B to charmonium decays generally deviate from the factorization predictions. We study rescattering effects mediated by intermediate charmed mesons in this class of decay modes and, in particular, we consider B^- → K^- h_c with h_c the J^PC=1^+- c̅ c meson, relating this mode to B^- → K^- χ_c0. We find B(B^- → K^- h_c) large enough to be measured at the B factories, hence this process could be used to study the poorly known h_c.
