Synthesis of Ru alkylidene complexes

The present work describes the robust synthesis of Ru alkylidene complexes (PCy(3))(2)Cl(2)Ru=CHR – precursors for metathesis catalysts. Moreover, the dynamic behavior of complexes where R = 2-naphthyl and 2-thienyl was studied. (1)H NMR techniques were employed to establish the preferred conformati...

Sumario:The present work describes the robust synthesis of Ru alkylidene complexes (PCy(3))(2)Cl(2)Ru=CHR – precursors for metathesis catalysts. Moreover, the dynamic behavior of complexes where R = 2-naphthyl and 2-thienyl was studied. (1)H NMR techniques were employed to establish the preferred conformations in solution for both complexes and the energy barrier for rotation around single (Ru=)CH–C(thienyl) bond was estimated (ΔG(≠)(303K) = 12.6 kcal/mol).
