Catalytic Asymmetric Reactions

Reductive alkylation of (R)-(+)-2,2'-diamino-1,1'-binaphthyl (1) with various ketones has been accomplished by means of NaBH4/H2SO4 in THF at room temperature. Bisalkylation predominated with the sterically less demanding acetone (1→3a; 82%), whereas the bulky 2-adamantanone afforded mainly the monoalkylated product 4c (71%). Both mono- and bisalkylated diamines (R)-3 and (R)-4 were reductively permethylated on reaction with CH2O, NaBH4, and H2SO4. The Pd(0)-catalyzed phenylation of (R)-(+)-1 with PhBr afforded the N,N'-diphenyl derivative (R)-7 (70%).

Manganese oxides are of more interest to researchers because of their ability as catalysts and lithium batteries. In this research, MnO2nanowires with diameter about 45 nm were synthesized by sol–gel method at room temperature (RT). Effect of increasing the annealing temperature from 400[Formula: see text]C to 600[Formula: see text]C on crystalline structure of nanostructure were studied and average crystallite size was estimated about 22 nm. X-ray Diffraction (XRD) method, Energy-Dispersive X-ray Diffraction (EDXD), Scanning Electron Microscopy (SEM) and Vibrating Sample Magnetometer (VSM) were used to characterize the nanowires of MnO2.
