1,3-Dimesityl-4,5-dihydro-1H-imidazol-3-ium chloride, cas is 173035-10-4, it is a common heterocyclic compound, the chiral-catalyst compound, its synthesis route is as follows.,173035-10-4
General procedure: An oven-dried Schlenk flask was charged with NHC salt 1 (2.49mmol) and evacuated for 30 min. The flask was then transferredinto a nitrogen-filled glove box and isolated KH (2.49 mmol)was added. The flask was then attached to a Schlenk line(argon/vacuum), evacuated once, and filled with argon. AnhydrousTHF (30 mL) was added, and the slow evolution of hydrogenwas observed. The resulting solution was then allowed tostir for 20 h at r.t. after which time the reaction mixture was filteredthrough a dry filter stick into an oven-dried Schlenk flask.The THF was evaporated, and the resulting free carbene wasextracted into anhydrous toluene (30 mL). The resulting toluenesolution was filtered through another dry filter stick into a previouslyevacuated and oven-dried Schlenk flask containing[(cod)Ir(py)2]PF6 (2, 1.66 mmol). The reaction was allowed tostir for 2 d at r.t. under an argon atmosphere. After this time, themixture was filtered to yield the desired iridium complex 3.
As the rapid development of chemical substances, we look forward to future research findings about 173035-10-4
