Abstract :

Oxidative coupling of amine to imine is very well-known process and has been extensively studied before. However, work on highly selective oxidative coupling is limited. In this work we have synthesized a molybdenum oxide mesoporous heterogeneous catalytic system. Through Brunauerâ??Emmettâ??Teller (BET) we confirmed that this material is mesoporous in nature. To check the crystallinity, X-ray diffraction was done and an orthorhombic cubic system was determined, which is different from commercially available molybdenum oxide which is monoclinic. Diffuse reflectance ultravioletâ??visible spectra show that there is a blue shift in the spectra compared to commercially available molybdenum oxide.
Scanning electron microscopy (SEM) and Tunneling electron microscopy (TEM) were done to study the morphology. This catalytic system was then used for amine coupling to form imines. Under very simple reaction conditions selectivities, conversions, and turn over numbers were observed to be very high.
