Vector charmonium states can be directly produced in the 
annihilation process. Among them, Y(4230) and Y(4360) splitting from the previously discovered Y(4260) are not easily arranged into the conventional charmonium spectrum, while recent studies have indicated that they have strong couplings to 
and 
In this work, we investigate the production of Y(4230) and Y(4360) as the heavy-quark spin symmetry doublet hadronic molecules of and 
in B decays via the triangle diagram mechanism. In particular, we propose that the decay constants of Y(4230) and Y(4360) extracted in B decays are useful for clarifying their nature.
