The invention provides a method of separating soluble organotin residue from a reduced product of a reduction reaction that uses an organotin hydride as a reducing agent, the method comprising: (i) contacting a reaction medium comprising said reduced product and soluble organotin residue with a substrate which, (a) is substantially insoluble in the reaction medium, (b) binds at least a portion of said soluble organotin residue, and (c) does not substantially bind the reduced product; (ii) separating said substrate from the reaction medium, thereby removing said at least a portion of organotin residue from the reaction medium; andrecovering the reaction medium comprising the reduced product. The invention also provides a method of performing a reduction reaction using an organotin hydride as a reducing agent that incorporates the method of separating soluble organotin residue.
