Abstract Latent metathesis catalysts equipped with boronate esters of diols as exchangeable end-groups on their NHC ligands and an S-chelated ruthenium-benzylidene core were synthesized. The stable S-chelated ruthenium complexes underwent hydrolysis under mild acidic conditions, allowing easy exchange of terminal units by several 1,2- and 1,3-diols, without degrading the central ruthenium benzylidene
