Abstract

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.
