Microwave-assisted route

Imidazo[l,2-c]thieno[3,2-e]pyrimidines were investigated as possible broncho dilatators. A facile microwave-assisted route for the synthesis of these tricyclic thieno derivatives was reported in quantitative yields via intermediate 4-chlorothieno[2,3-d]pyrimidines themselves synthesized under one-pot reaction conditions. The last step was performed for only 1 min... 

The last example cited involves the microwave-assisted route towards novel 5-substituted-2,3-dihydroimidazo [1,2-c] thieno [3,2-e] pyrimidines described by Rao and co-workers. Employing microwave heating and an easy work-up procedure, the products were obtained in improved yields over the conventional methods (Scheme 3.53)83.

The use of microwave-assisted routes to metal oxide nanoparticles is gaining increasing attention in recent years. Microwave irradiation works through two... 

The same group developed a one-pot microwave-assisted route to Sn02/RG0 composites using benzyl alcohol as a reactant for metal oxide formation and reducing agent for partial reduction of graphene oxide. Platinum nanoparticles... 

Microwave-Assisted Route Towards Fluorinated Nanomaterials 41... 

Here again, the use of microwave-assisted route enables the synthesis of a new series of Ti-based fluoride nanomaterials at low duration time and low temperature. Beside, the report of a phase derived from the HTB-type structure, the synthesis conditions favour the competition between OH and F ions, leading to new compositions besides TiOF2, the only titanium oxyfluoride reported so far by various authors through various synthesis...

Microwave-assisted route for the synthesis of nanomaterials has gained importance in the field of synthetic technology because of its faster, cleaner and cost effectiveness than the other conventional and wet chemical methods for the preparation of metal oxide nanoparticles. Synthesis of metal oxide nanoparticles, for example, y-Fe Oj, NiO, ZnO, CuO, Co-y-FejOj was carried out by microwave-assisted route through the thermal decomposition of their respective metal oxalate precursors employing polyvinyl alcohol as a fuel (Lagashetty et al., 2007).
