资源简介：
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.
