Suzuki Miyaura Cross Coupling
The Suzuki-Miyaura cross-coupling reaction is one of the most important and highly utilized reactions in organic chemistry, with applications in polymer science as well as in the fine chemicals and pharmaceutical industries.
Chiral Disulfonimides for Asymmetric Counteranion-directed Catalysis (ACDC)
Asymmetric counteranion-directed catalysis (ACDC) has a number of valuable applications in enantioselective synthesis.
MCAT- 53™ Catalyst for Ruthenium Formation
A recyclable, ligand-free ruthenium catalyst for C–H activation reactions and concomitant C–C bond formation in the presence of water.
Molecular Sieves
Molecular sieves are crystalline metal aluminosilicates having a threedimensional interconnecting network of silica and alumina tetrahedra. Natural water of hydration is removed from this network by heating to produce uniform cavities which selectively adsorb molecules of a specific size.
Dinuclear Zinc Catalysts
The aldol reaction is arguably one of the most important C–C bond forming reactions in the synthesis of complex molecules.
Umicore Precatalysts
We are happy to offer a series of precatalysts for asymmetric catalysis and Pd based cross coupling catalysis. Our partnership with Umicore allows us to offer a portfolio of metal complexes with batch-to-batch consistency for a plethora of catalytic reactions.
N-Heterocyclic Carbenes
Echavarren and co-workers have also demonstrated the utility of Au-NHCs in the reactions of 1,6-enynes. They determined that the outcome of the cyclization of 1,6-enyne 1 was dependent on the ligand coordinated to the metal. When 2 was used in...
Scale-Up Guide: Buchwald-Hartwig Amination Reaction
All of the preformed catalysts used in the kit are air and moisture stable complexes in their commercially available form. Once activated by base under the reaction conditions they become sensitive to air. To best enable scale-up success, the use...
Hydroazidation Catalyst
The chemistry of organoazides is exceedingly rich, since the azide functionality reacts with electrophiles, nucleophiles, and dipolarophiles, with or without the extrusion of dinitrogen. Common place transformation such as Staudinger reductions or ligations, Cu(I)-catalyzed Huisgen cycloadditions (of the “click”...

Asymmetric Allylboration Using Ipc2B(allyl)
Asymmetric allylboration of aldehydes is an extremely important method for preparation of homoallylic alcohols, as evidenced in numerous complex natural product syntheses.
Buchwald GT Capsules for Cross-Coupling
The advent of the Buchwald portfolio of ligands and complexes for cross-coupling reactions in the past decade has greatly advanced the ease of performing this transformation.
Preparing Terminal Alkynes: Vinyl N,N-Diisopropylcarbamate for Stereospecific Alkynylation of Chiral Boronic Esters
Prof. Aggarwal et al developed a stereospecific alkynylation of chiral secondary & tertiary pinacol boronic esters, allowing the facile preparation of terminal alkynes.
C-O Cross-Coupling of Activated Aryl and Heteroaryl Halides with Aliphatic Alcohols
JosiPhos CyPF-tBu and palladium give catalyst for alkoxylation of activated heteroaryl halides with primary, secondary, and tertiary alcohols
DalPhos Ligands
DalPhos is air-stable and contains the bulky di(1-adamantyl)phosphino [P(1-Ad)2] fragment. These ligands are useful in Pd-catalyzed C-N and C-C bond formation. Both Me-DalPhos and Mor-DalPhos allow for Pd-catalyzed ammonia, hydrazine and acetone cross-coupling with good functional group tolerance
G3 and G4 Buchwald Precatalysts
G3 and G4 Buchwald palladium precatalysts are the newest air, moisture, and thermally stable crossing-coupling complexes used in bond formation for their versatility and high reactivity.
