Several ruthenium-based catalysts of the formula [RuX (arene)(L)] have been synthesized, and relative catalyst activities were determined by monitoring the atom transfer radical polymerization (ATRP) of methyl methacrylate. The following order of increasing activity was determined: X = I < B r < Cl and L = P P h
