Mode opératoire

This compound was prepared in situ as described above. In a typical experiment, benzylthio ethanamine (0.2 g, 1.2 mmol) was dissolved in toluene (5 ml) and the solution was then added to a suspension of dichloro 1,5-cyclooctadiene ruthenium polymer [RuCl2(COD)]n in toluene (5 ml). The mixture was then stirred under argon at 100° C. for 2 hours. The solvent volume was reduced in vacuo to approximately 3 ml and a solid was precipitated by adding ether (10 ml) to obtain a reddish brown product. The activities of these catalysts are low for the hydrolysis of ammonia borane. The reactions with cobalt(II)chloride (CoCl2) and chlorobis(cyclooctene)iridium(I)dimer [IrCl(COE)2]2 were performed similarly. The three catalysts prepared in the section (section b) were all tested for ammonia borane hydrolysis.
