Morozov, Oleg S. published the artcileHydrohydrazination of Arylalkynes Catalyzed by an Expanded Ring N-Heterocyclic Carbene (er-NHC) Gold Complex Under Solvent-Free Conditions, COA of Formula: C9H8N2O, the main research area is aryldiazepinylidene gold carbene complex preparation mol crystal structure; diastereoselective hydroamination aryl alkyne hydrazine aryldiazepinylidene gold complex catalyst; hydrazone stereoselective preparation green chem solvent free; aryl alkyne hydrazine hydrohydrazination gold carbene catalyst; expanded ring nitrogen heterocyclic carbene gold complex catalyst.
The gold carbene complex [(THD-Dipp)AuOTf], containing the strongly electron donating, sterically bulky 1,3-bis(2,6-diisopropylphenyl)hexahydro-2H-1,3-diazepine-2-ylidene ligand, was an effective catalyst for the stereoselective hydroamination of aryl alkynes with tosylhydrazine and tert-Bu carbazate under solvent-free conditions to give (E)-tosyl and Boc hydrazones. The structure of (THD-Dipp)AuOTf was determined by X-ray crystallog.
