The invention concerns a method of preparing trialkyl-tin hydrides by a process that ensures outstanding long-term stability. bis-[Trialkyl-tin) oxides are dissolved in a solvent that mixes only to some extent if at all with water and converted with an aqueous solution of sodium borohydride stabilized with a base. The product is obtained by phase separation and optionally by distillation. The trialkyl-tin hydride is obtained almost quantitatively with a yield of more than 95 %.
