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+– meson, relating this mode to B – → K – χ c0. We find large enough to be measured at the B factories, hence this process could be used to study the poorly known h c .
