The observation of CP violation has been experimentally verified in numerous B decays but is yet to be confirmed in final states with half-spin particles. We focus our attention on baryonic B-meson decays mediated dominantly through internal W-emission processes and show that they are promising processes to observe for the first time the CP violating effects in B decays to final states with half-spin particles. Specifically, we study the 
and 
decays. We obtain 
, in agreement with current data, and 
. Furthermore, we find 
. With measured branching fractions 
, we point out that 
can be new observables for CP violation, accessible to the Belle II and/or LHCb experiments.
