Abstract

An improved one-pot synthesis of olefin metathesis catalysts (PCy3)(L)Ru=CHPhCl2 (L = N-heterocyclic nueleophilic carbene: IMes, 3; SIMes, 4) employs potassium tert-amylate to deprotonate the imidazolium salt ligand precursor. Both of the reaction steps are carried out using a one-pot protocol in hexane with commercially available reagents under mild conditions, permitting the isolation of 3 and 4 by simple filtration.
