Popis: When an 2-isopropoxy-substituted benzylidene ligand of a Hoveyda-type Ru-metathesis complex is modified by an additional 4-diethylamino group and treated wit PTSA it yields a highly active precatalyst suitable for RCM, cross metathesis, and enyne metathesis. The important property of this ammonium tagged Ru-complex is associated with the possibility of its easy removal by a simple filtration protocol.
