RESUMEN
Through the simple expedient of using a mixture of KF and silica as the stationary phase in column chromatography, levels of organotin impurities from tributyltin hydride mediated reductions have been reduced from stoichiometric levels to approximately 30 ppm.

RESUMEN
The combination of (Bu(3)Sn)(2) and TBAF has been shown to reduce aromatic bromides and iodides in excellent yields under mild conditions. When the residual water in TBAF is exchanged for D(2)O, the halogen is replaced by a deuterium atom.
