Abstract
We present recent results in semileptonic and non-leptonic exclusive Bc decays to charmonium states both in S-wave, J/ψ and ηc, and in P-wave, χcJ and hc. The analysis, based on the heavy quark spin symmetry (HQSS), produces relations among form factors that parametrize the hadronic matrix elements in the amplitudes of the decays. These relations are helpful to control the hadronic uncer- tainty affecting these processes. Furthermore, Bc decays allow us to get hint on the structure of states like χc1(3872), whose exotic or ordinary charmonium nature is debated.
