The ammonium tagged Hoveyda-type catalyst bearing sterically enlarged N-heterocyclic carbene ligand was synthesized and supported on SBA-15. The obtained heterogeneous olefin metathesis catalyst forms unprecedentedly stable Ru-methylidenes and provides products of ring-closing and cross metathesis with turnover numbers (TONs) up to 35 000 and turnover frequencies (TOFs) up to 1590 min(-1). The catalyst proved to be truly recyclable and effective in a continuous flow mode.
