An overview is given on new measurements of B → ηcK branching fractions with the ηc meson reconstructed in the KS0K+π-, K-K+π0, K*0K-π+, and p̄p channels. These signals are large enough to be used to determine the mass and width of the ηc meson. Furthermore, the first observation of the related decay mode B0 → ηcK*0 is discussed. When K*0 → KS0π0, this decay mode is also a CP eigenstate.
