ChemInform Abstract: An Efficient and Solvent-Free One-Pot Synthesis of Nitriles from Aldehydes.

One-pot synthesis of aromatic nitriles from aldehydes using magnetic material separated from coal fly ash

An efficient and simple procedure for the direct synthesis of Aromatic Nitriles from Aldehydes, Hydroxylamine Hydrochloride is described using magnetic material separated from coal fly ash. Coal fly ash is a waste material generated in huge amount by burning of coal for the generation of electricity in thermal power station. It contains SiO2, Al2O3 and magnetic material in significant amounts, ...

nano-ticl4.sio2 promoted one-pot synthesis of amides or nitriles from aldehydes

this research proposes an efficient and easy procedure for the preparation of amides or nitriles from aldehydes. such materials were prepared via one-pot three component condensation reaction of various aldehydes in the presence of nano-ticl4.sio2 as a catalyst under thermal conditions. all reactions proceeded in high yields and in a moderately short reaction time. meanwhile, oximes were obtain...

Sodium Bismuthate: An Efficient Catalyst for the One-pot Synthesis of Biologically Active Spiro[4H-pyran] Derivativesunder Solvent-free Conditions

An efficient sodium bismuthate (NaBiO3) synthesis of biologically active spiro[4H-pyran]derivatives has been accomplished via one-pot three-condensation of isatin/acenaphthequinone, malononitrile and different reagents including 1,3-dicrbonyl compounds, α-naphthol and 4-hydroxycumarin under solvent-free conditions. The notable advantages of the present procedure are: eco-friendly, environmental...
