Leptonic B decays provide theoretically clean probes that are sensitive to physics beyond the standard model. These decays can be accessed at high luminosity \(e^+e^-\) colliders operating near the \(\varUpsilon (4S)\) resonance, where kinematic constraints and the nearly \(4\pi \) solid angle coverage of the Belle and BaBar detectors allow for clean measurements of final states that involve non-interacting particles. Charged B decays to lepton pairs will be reviewed, with emphasis on two recent Belle measurements. In addition, a search for the flavour-changing neutral-current decay \(B^-\rightarrow \varLambda \overline{p}\nu \overline{\nu }\) from BaBar will be presented.
