格拉布斯和格拉布斯-霍维达第二代预催化剂在一系列溶剂中的起始率已被准确测量。溶剂变色拟合揭示了两种前催化剂对关键溶剂参数的不同依赖关系，这与GRubbs和GRubbs-Hoveyda前催化剂启动的不同机理一致。
Initiation rates for Grubbs and Grubbs-Hoveyda second generation pre-catalysts have been measured accurately in a range of solvents. Solvatochromic fitting reveals different dependencies on key solvent parameters for the two pre-catalysts, consistent with different mechanisms by which the Grubbs and Grubbs-Hoveyda pre-catalysts initiate.
