Microwave-assisted synthesis of metalloporphyrazines
Tetrahedron Letters, 2007The synthesis of metalloporphyrazines with enhanced yields directly from substituted maleonitriles is described. The one-step procedure involves tetramerization using hexamethyldisilazane, p-toluenesulfonic acid and DMF in a sealed tube under microwave irradiation.

Microwave-assisted synthesis of corroles
Tetrahedron Letters, 2003The recently developed Gross's method for the synthesis of corroles has been modified and successfully applied to the preparation of new free base tris-aryl- and tris-pyrimidyl-corroles using solvent-free conditions and microwave irradiation. Compared to conventional heating, the microwave technique afforded an increase in corrole yields of ca. 30% and

Microwave‐Assisted Synthesis of Azocalixarenes
Synthetic Communications, 2007Abstract Five new water‐soluble and two water‐insoluble azocalixarenes have been synthesized by coupling reaction of different substituted anilines and terta hydroxylcalix[4]arene. These dyes have been characterized by 1H NMR, 13C NMR, FAB mass, and elemental analysis.

Microwave-assisted synthesis using ionic liquids
Molecular Diversity, 2009The research and application of green chemistry principles have led to the development of cleaner processes. In this sense, during the present century an ever-growing number of studies have been published describing the use of ionic liquids (ILs) as solvents, catalysts, or templates to develop more environmentally friendly and efficient chemical ...
