[ 1 ] - Synthesis and New Synthetic Utility of some (Hetero)aryl Azido Compounds under Thermal and Ultrasonic Irradiation
Some aryl and heteroaryl azido compounds were synthesized from the reaction of corresponding fluoro and chloro compounds with sodium azide in DMF as solvent and under various reaction conditions especially ultrasonic irradiation. Reaction of aromatic and heteroaromatic azido compound with thioacetic acid in the presence of sodium hydrogen carbonate and in methanol as solvent led to the differen...
[ 2 ] - One-pot Multi-step Synthesis of some Aromatic Salicylaldoximes Using MgO Nanoparticles
MgO nanopartticels (NP-MgO) in average size between 30—130 nm were prepared by sonochemistry method. Some phenols have been converted to ortho-hydroxybezaldehyd by ortho-formylation using MgO nanoparticles and (CH2O)n in xylene and subsequently treated with aqueous NH2OH.HCl, affording the corresponding aldoxime in a one-pot procedure. Moreover, this one-pot process, with two transformations, o...
[ 3 ] - Ultrasound Promoted Efficient Synthesis of some Amides from Nitriles in Ambient Condition
Some amide derivatives have been synthesized by the reaction of corresponding nitriles with potassium tert-butoxide as a nucleophilic oxygen source under ultrasonic irradiation. This new methodology provides good to excellent yields in short reaction times (15-90 min) at room temperature.
[ 4 ] - Synthesis and Pesticide Activity of some New Arylic and Pyridylic Oxime Ether Derivatives of Ionone
Some oxime ether derivatives of α-ionone (4-(2,6,6-trimethyl-2-cyclohexen-1-yl)-3-buten-2-one) have been synthesized. Reaction of 4-(2,6,6-trimethyl-2-cyclohexen-1-yl)-3-buten-2-ketoxime with various chloro and fluoro aromatic and hetero aromatic compounds gave the corresponding oxime ether derivatives via aromatic nucleophilic substitution (SNAr). The structures of these co...
[ 5 ] - Rapid and Green Synthesis of some Benzothiazole-, Benzimidazole- and Benzoxazole-2-thiol Derivatives Using Copper Sulfate in Aqueous Media
In this study an easy, green, efficient and simple approach is reported for the synthesis of some benzothiazole-, benzimidazole- and benzoxazole-2-thiolderivatives. The proposed approach employs the reaction of corresponding aromatic amine with potassium isopropyl xanthate (Z11) in the presence of copper sulfate (CuSO4) as a catalyst under conventional heating and ultrasonic irr...
