Efficient light- and thermal-activated metathesis reactions of tetra-substituted olefins were obtained by the S-chelated ruthenium precatalyst Tol-SCF3. Its reactivity in a series of benchmark olefin metathesis reactions was compared to previously reported Mes-SCF3 and a novel sterically congested S-chelated complex, Dipp-SCF3. Tol-SCF3 is thus the first latent catalyst proven to be capable of promoting olefin metathesis of demanding substrates upon light stimulation at room temperature.

受光和热激活的受阻基质的烯烃复分解。
通过S螯合的钌预催化剂Tol-SCF 3获得了四取代烯烃的有效的光活化和热活化复分解反应。将其在一系列基准烯烃复分解反应中的反应性与先前报道的Mes-SCF 3和新型空间拥挤的S螯合复合物Dipp-SCF 3进行了比较。因此，Tol-SCF 3是第一种潜在催化剂，被证明能够在室温下刺激光后促进所需底物的烯烃复分解。
