2425 Electronic vs. Steric Hindrance Effects in Amine Ligands to
Ru-Based Initiators for ROMPTiago B. Silva, Ricardo S. Camargo and
Benedito S. Lima-Neto
Graphical Abstract[RuCl2(PPh3)2(amine)x]-type complexes, with
NH2Ph (1; x = 2), NH2Bz (2;
x = 2) and NHBuPh (3; x = 1), in the presence of
ethyldiazoacetate (EDA), were investigated for ring-opening
metathesis polymerization (ROMP) of
cyclic olefins. The reactivity of the complexes according to the
electronic density and steric hindrance of the amines as ancillary
ligands was
discussed. In the series, complex 3 is the most active at 25 °C
for 5 min, probably because there is more steric hindrance due to
the number and
the bulkiness of the amine, even with a lower s-donor
character
