Synthesis and evaluation of new RuCl2(p-cymene)(ER2R') and (eta(1):eta(6)-phosphinoarene)RuCl2 complexes as ring-opening metathesis polymerization catalysts
[en] New RuCl2(p-cymene)(ER2R') complexes (E = P, As, Sb; R, R' = H, alkyl, arylalkyl) have been synthesized and used as catalyst precursors for the ring-opening metathesis polymerization (ROMP) of cyclooctene, cyclopentene, and norbornene. When ER2R' was a phosphinoarene, the p-cymene ligand could be displaced upon heating and tethered (eta(1):eta(6)-phosphinoarene)RuCl2 complexes were obtained. Simple thermogravimetric analysis (TGA) of the complexes provided clear-cut indication on their potential catalytic activity in ROMP. (C) 2000 Elsevier Science S.A. All rights reserved.
