Ammonium chloride catalyzed microwave-assisted synthesis of tetrahydrobenzo[b]pyrans
In the present work, we have developed a mild, efficient, and environmentally benign method for the synthesis of tetrahydrobenzo[b]pyran derivatives via a three-component cyclocondensation of aldehydes, malononitrile and dimedone utilizing ammonium chloride as a simple, easily available and cost effective catalyst under microwave irradiation. This method has several attracting features such as ...

متن کاملAn expeditious synthesis of N-substituted pyrroles via microwave-induced iodine-catalyzed reactions under solventless conditions.
An expeditious synthesis of N-substituted pyrroles has been developed by reacting 2,5-dimethoxy tetrahydrofuran and several amines using a microwave-induced molecular iodine-catalyzed reaction under solventless conditions.
متن کاملTetra-N-Butyl ammonium hydroxide mediated one-pot synthesis of pyrano [2, 3-d] pyrimidinone Derivatives
Tetra-N-Butyl Ammonium Hydroxide was used as a catalyst for one-pot, three component condensation reactions consisting of aromatic aldehydes, malononitrile and barbituric acid in ethanol:water solvent system at 60oC. Current method has major advantages like mild reaction conditions with simple operation, high yields, by using a less toxic and lower costlier catalyst.In conclusion, we have explo...
متن کاملSynthesis 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.
