Electric Literature of 68737-65-5, Because a catalyst decreases the height of the energy barrier, its presence increases the reaction rates of both the forward and the reverse reactions by the same amount.68737-65-5, Name is (1R,2R)-N,N’-Dimethyl-1,2-cyclohexanediamine, molecular formula is C8H18N2. In a article，once mentioned of 68737-65-5
A series of p-nitroanisole-containing tetraazacrown (14-18), diazacryptand (22), and diazadithia-crown (23-25) macrocycles has been prepared by treating the appropriate secondary diamine, diazacrown, or dimercaptan with 2,6-bis[(2-chloroacetamido)methyl]-4-nitroanisole (BB). Five of these p-nitroanisole-containing macrocycles were reported earlier. Four new bis(p-nitroanisole)-containing macrocycles resulting from a 2 + 2 macrocyclization of diamine or dimercaptan with BB were also isolated. Six of the p-nitroanisole-containing macrocycles (16, 17, 22-25) were converted to the p-nitrophenol-containing macrocycles (27-32) on treatment with LiI in refluxing pyridine. Thermodynamic quantities (log K, DeltaH, and TAS) for the interactions of four new compounds (24, 27, 31, and 32) with Na+, K+, Ba2+, Ag+, and Pb2+ were evaluated by calorimetric titration at 25.0 C in either 70% or absolute methanol solution. The compounds show strong interactions with Ag+ and Pb2+ but very weak interactions with Na+, K+, and Ba2+. Ligand 31 exhibited high selectivity for Ag+ over Pb2+. X-ray crystal structures were obtained for diazadithia macrocycle 23 and the Ag+-31 complex.
We’ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, the role of 68737-65-5, and how the biochemistry of the body works.Electric Literature of 68737-65-5
