Abstract
Sm(bipy)(glycine)3 [bipy = 2,2-bipyridine] was synthesized by classic, microwave and mechanical methods. UV-Vis reveals a strong signal near 190 nm corresponding to a high energy Sm-O bond and f→f transitions. FT-IR spectra show a band between 490 - 450 cm-1 indicative of a Sm-O bond. TGA-DTA and MS analytical analysis, confirm the structural proposals. The samarium (III) complex was tested in 1-hexene hydrogenation, in biphasic media (cyclohexane/water) and the reaction parameters were optimized (time, temperature, substrate/catalyst ratio and H2 pressure). Catalystshowed 37.5 % conversion.
