Resumo: We study hadronic annihilation decays of B mesons within the perturbative QCD at collinear approximation. The regulation of endpoint divergences is performed with the help of an infrared finite gluon propagator characterized by a non-perturbative dynamical gluon mass. The divergences at twist-3 are regulated by a dynamical quark mass. Our results fit quite well the existent data of B-0 --> Ds-K+ and B-0 --> D-s(-)*(K) over bar (+) for the expected range of dynamical gluon masses. We also make predictions for the rare decays B-0 --> K-K+, B-s(0) --> pi-pi+, pi(0)pi(0), B+ --> D-s(()*()+)(K) over bar (0,) B-0 --> D-s(+/-()*K-)(-/+) and B-s(0) --> D-+/-(*())pi(-/+), D-0 pi(0).
