The best results were obtained at 40°C under a hydrogen pressure of 20 bar (conversion 100%, selectivity N 99%). After a total turnover number of 1423, the hectorite supported ruthenium nanoparticles are deactivated but can be recycled and regenerated.

Arene ruthenium complexes containing long-chain N-ligands L 1 = NC 5 H 4 -4-COO-C 6 H 4 -4-O-(CH 2 ) 9 -CH 3 or L 2 = NC 5 H 4 -4-COO-(CH 2 ) 10 -O-C 6 H 4 -4-COO-C 6 H 4 -4-C 6 H 4 -4-CN derived from isonicotinic acid, of the type These complexes and nanoparticles show a high anticancer activity towards human ovarian cell lines, the highest cytotoxicity being obtained for complex 2 (IC 50 = 2 lM for A2780 and 7 lM for A2780cisR).
