WebThe experimental difference in the reactivities of cationic catalysts in a representative intramolecular hydroamination reaction shows how a cationic Ir–Ag adduct can fail to deliver the reaction product through what appears to be a stabilization of the catalytically inactive iridium–silver intermediate by the educt. Supporting Information WebIn organic chemistry, triflate (systematic name: trifluoromethanesulfonate), is a functional group with the formula R−OSO 2 CF 3 and structure R−O−S(=O) 2 −CF 3.The triflate group is often represented by −OTf, as opposed to −Tf, which is the triflyl group, R−SO 2 CF 3.For example, n-butyl triflate can be written as CH 3 CH 2 CH 2 CH 2 OTf. The corresponding …

WebJun 7, 2024 · The additional methylation to precursor 2 (OTf)2 results only in small changes of the geometrical parameters. While the torsion of the dimethylamino group is larger (48.2 (1)°) compared to 1I, the bonds of C2 to the three N atoms are hardly affected (range 133.6–136.5 pm). WebCyclooctadiene iridium chloride dimer is an organoiridium compound with the formula [Ir (μ 2 -Cl) (COD)] 2, where COD is the diene 1,5-cyclooctadiene (C 8 H 12 ). It is an orange-red solid that is soluble in organic solvents. The complex is used as a precursor to other iridium complexes, some of which are used in homogeneous catalysis.
