We study the observed B^-→ X(3823)K^- decay via rescattering mechanism and show that this branching ratio is well reproduced by this mechanism. We further extend this theoretical framework to investigate the decays of B^-→η_c2 (^1D_2)/ψ_3(^3D_3)K^-, where the η_c2 (^1D_2) and the ψ_3(^3D_3) are D-wave charmonium partners of the X(3823). Our results show that the branching ratios, B^-→η_c2(^1D_2) K^- and B^-→ψ_3(^3D_3) K^-, are of the order of 10^-5, which can be accessible at LHCb, Belle and forthcoming BelleII.
