Combining an acid activated precatalyst with a photoacid generator (PAG) in the presence of ultraviolet light resulted in a highly efficient catalyst for olefin metathesis. The tandem system of precatalyst and PAG was capable of both ring closing metathesis (RCM) and ring opening metathesis polymerization (ROMP) in good to excellent conversion. Mechanistic investigations revealed that the catalytically active species is very similar to that of other well-known Ru-based catalysts.
在紫外线存在下，将酸活化的预催化剂与光酸发生器（PAG）相结合，可得到一种用于烯烃复分解反应的高效催化剂。预催化剂和PAG的串联体系能够以良好至优异的转化率进行闭环复分解反应（RCM）和开环复分解聚合反应（ROMP）。机理研究表明，催化活性物种与其他著名的钌基催化剂非常相似。
