Five pairs of novel chiral alc. functionalized gold(I) and gold(III) NHC complexes derived from chiral amino alcs., were synthesized and characterized (NMR, IR, HRMS). Single crystal x-ray diffraction data of gold(I) and gold(III) complexes are reported and discussed. The chiral imidazolium preligands were readily synthesized via the oxalamides, subsequent reduction and final orthoformate condensation. An improved method was used for generation of gold(I) NHC complexes (up to 92%) and further oxidation afforded the corresponding gold(III) NHC complexes (up to 99%). All the Au(I) and Au(III) NHC complexes proved far more catalytically active in a 1,6-enyne alkoxycyclization test reaction than our previously tested N,N- and P,N-ligated Au(III) complexes. Comparative gold(I) and gold(III) catalytic studies demonstrated different catalytic ability, depending on the NHC ligand flexibility and bulkiness. Excellent yields (92-99%) of target alkoxycyclization product were obtained with both gold(I) and gold(III) complexes with the bulky N1-Mes-N2-ethanol based NHC ligand. In the experimental materials used by the author, we found (1S,2R)-1-Amino-2,3-dihydro-1H-inden-2-ol(cas: 126456-43-7Recommanded Product: 126456-43-7)
(1S,2R)-1-Amino-2,3-dihydro-1H-inden-2-ol(cas: 126456-43-7) belongs to anime. Reaction with nitrous acid (HNO2), which functions as an acylating agent that is a source of the nitrosyl group (―NO), converts aliphatic primary amines to nitrogen and mixtures of alkenes and alcohols corresponding to the alkyl group in a complex process. This reaction has been used for analytical determination of primary amino groups in a procedure known as the Van Slyke method.Recommanded Product: 126456-43-7
