Recommanded Product: (1S,2R)-1-Amino-2,3-dihydro-1H-inden-2-olThis research focused ontitanium hydroxyindanylaminopentenone complex preparation cycloaddition catalyst; crystal structure titanium hydroxyindanylaminopentenone. The article conveys some information:
New titanium complexes, TiLCl2(THF) and TiL2, containing the tridentate chiral Schiff-base ligand, L, prepared from the condensation reaction of 2,4-pentadione and (1R,2S)-(-)-1-aminoindanol, were synthesized and characterized by various anal. methods including X-ray crystallog. Ligand L acted as a dianionic tridentate ligand and, owing to a chiral center in the aminoindanol part, imparted chirality to its titanium complexes. The newly synthesized titanium complexes and previously reported analogous Ti complexes were used as catalysts in the cycloaddition of CO2 to propylene oxide as the first representatives of titanium complexes with tridentate Schiff base ligands to have been used for this purpose. These complexes provided high selectivity toward cyclic propylene carbonate (>99%) and showed considerable activities with TOF values up to 131 h-1 in comparison with the previously reported catalyst systems. After reading the article, we found that the author used (1S,2R)-1-Amino-2,3-dihydro-1H-inden-2-ol(cas: 126456-43-7Recommanded Product: (1S,2R)-1-Amino-2,3-dihydro-1H-inden-2-ol)
(1S,2R)-1-Amino-2,3-dihydro-1H-inden-2-ol(cas: 126456-43-7) belongs to anime. Many important products require amines as part of their syntheses. Methylamine is utilized in the production of the analgesic meperidine (trade name Demerol) and the photographic developer Metol (trademark), and dimethylamine is used in the synthesis of the antihistamine diphenhydramine (trade name Benadryl), the solvent dimethylformamide (DMF), and the rocket propellant 1,1-dimethylhydrazine. The synthesis of the insect repellent N,N-diethyl-m-toluamide (DEET) incorporates diethylamine while that of the synthetic fibre Kevlar requires aromatic amines.Recommanded Product: (1S,2R)-1-Amino-2,3-dihydro-1H-inden-2-ol
