Ring-Closing Alkyne Metathesis (RCAM)
Alkyne metathesis has been a useful tool for C–C bond formation since the discovery of structurally well-defined metal alkylidynes by Schrock and coworkers.
Rieke® Highly Reactive Metals
Metal-enhanced organic synthesis via organometallic intermediates is a widely used preparative route for thousands of organic compounds.
Rh2(esp)2 Catalyst
New! Rh2(esp)2, and exceptionally efficient and selective catalyst for C-H amination.
Ring Opening Metathesis Polymerization
ROMP has become an important reaction for the formation of well defined polymers. Ziegler and Natta's early studies on ethylene and polypropylene polymerization lead to extensive research efforts on the investigation of transition metal catalyzed polymerization and its mechanism, which...
TPGS-750-M: Second-Generation Amphiphile for Organometallic Chemistry in Water at Room Temperature
Lipshutz and co-workers have recently developed a second generation technology to their original PTS-enabling surfactant based on the polyoxyethanyl-α-tocopheryl succinate derivative, TPGS-750-M.
CBILS©
The use of CBILS© – Carbonate Based Ionic Liquid Synthesis – developed by the Austrian company proionic, offers one of the simplest, yet most elegant synthetic methods for the production of ionic liquids

Metathesis
Olefin metathesis is now a well-entrenched synthetic technique, and is a powerful method for the clean construction of innumerable classes of chemical architectures.
N-Heterocyclic Carbene (NHC) Ligands
Emerging class of privileged ligands
N-Heterocyclic Carbene (NHC) Ligands
Rapid progress in cross-coupling reactions of unactivated substrates catalyzed by metal complexes has transformed the chemical market-place through introduction of an extensive library of achiral and chiral phosphine ligands.
N-Heterocyclic Carbene (NHC) Compounds
Rovis has demonstrated that triazolium salt in the presence of a base can act as an N-heterocyclic carbene organocatalyst1 in highly enantioselective intramolecular Stetter reactions.
