Description

2-[2,6-Bis(1-Methylethyl)Phenyl]-3,3-Dimethyl-2-Azoniaspiro[4.5]Dec -1-Ene Hydrogen Dichloride, Min. 97% Cyclohexyl-CAAC is a high-purity, cyclic (alkyl)(amino)carbene (CAAC) ligand precursor, a specialized class of N-heterocyclic carbene (NHC) known for its exceptional steric bulk and strong σ-donating properties. This compound matters for researchers and manufacturers developing advanced catalysts for challenging organic transformations, including cross-coupling, olefin metathesis, and C-H activation, where traditional phosphine or imidazolylidene ligands fail. It is essential for the pharmaceutical, agrochemical, and materials science industries seeking to improve catalytic efficiency, selectivity, and stability in complex synthetic routes.

Application

• Homogeneous Catalysis: As a precursor for generating highly active and robust CAAC ligands in transition metal catalysis (e.g., Ru, Pd, Au, Ni complexes).
• Olefin Metathesis: Key component in the synthesis of next-generation Grubbs-type and Hoveyda-Grubbs catalysts for ring-closing (RCM), cross (CM), and ring-opening metathesis polymerization (ROMP).
• Pharmaceutical Intermediate Synthesis: Enables efficient and selective catalytic steps in the production of complex active pharmaceutical ingredients (APIs).
• Polymer Science: Used in catalyst systems for the controlled polymerization of olefins and other monomers to create novel polymeric materials.
• Organometallic Research: A critical building block for academic and industrial R&D into new catalytic systems and reaction mechanisms.
• Fine Chemical Production: Facilitates high-yield, low-waste synthetic processes for specialty chemicals and agrochemical intermediates.
