Abstract:The catalytic influence of inorganic salts, polarity of solvent and addition of chosen additivities on
free radical reactions of tin hydrides has been reviewed. There have been collected examples of different reactions
as hydrostannation of alkynes with mixed tin hydrides as well as enantioselective reductions of derivatives
of 2-bromo-2-arylpropionates, α-iodocoumarin and acetophenone with tin hydrides. For all of them
the steric effect may be improved by the addition of inorganic salts. They have been discussed examples of
tandem radical macrocyclisations and reactions of -amide radicals depending on polarity of solvent. They have been also
presented examples of hydrostannation of methylenecycloprpanes effected by the addition of additivities.
