Synthesis of Metallophthalocyanines Under Solvent Free Conditions Using Microwave Irradiation
Phthalocyanine complexes of Cu, Co, Ni, Fe, Zn, Pd, Pt and Ru have been synthesized from reaction between phthalonitrile and proper metal salts upon exposure to microwave irradiation under solvent-free conditions and considerably reduced reaction times.

متن کاملSynthesis of electron-poor N-Vinylimidazole derivatives catalyzed by Silica nanoparticles under solvent-free conditions
Protonation of the highly reactive 1:1 intermediates, produced in the reaction between triphenylphosphine and acetylenic esters, by NH-acids such as azathioprine, imidazole or theophylline leads to the formation of vinyltriphenylphosphonium salts, which undergo a Michael addition reaction with a conjugate base to produce phosphorus ylides. Silica nanoparticles (silica NPs were prepared by therm...
