Ultrasound assisted oxidation of various alcohols to corresponding aldehydes by using Al2O3 as catalyst
A convenient approach for oxidation of structurally diverse alcohols has been developed using KMnO4 as oxidant agent in the presence of a catalytic amount of Al2O3 in aqueous acetonitrile. In this method various alcohols generally afforded the corresponding carbonyl compounds directly in good to high yield under ultrasound irradiation conditions. It shows that this kind of catalysis system is v...

متن کاملEffects of 2-Alkylamino-Substituted Dihydropyridines on Rabbit Jejunum
In order to investigate the effects of dimethylamino substituent at postion 2 of the dihydropyridine nucleus on its activity, dialkyl 1,4-dihydro-2-[2-(dimethy- lamino) ethyl]-6-methyl-4-(1-benzyl-2-alkylthio-5-imidazolyl)-3,5-pyrdinedicar- boxylates (6a-f) were synthesized. The synthesis was started from dialkyl 1,4- dihydro-2,6-dimethyl-4-(1-benzyl-2-alkylthio-5-imidazolyl)-3,5-pyridine...
متن کاملOxidation of Hantzsch 1,4- Dihydropyridines to Pyridines with Thallium Triacetate
Hantzsch 1, 4-dihydropyridines (1,4-DHPs) can be oxidized to the corresponding pyridine derivatives by thallium triacetate in high yields.
متن کاملPhotochemical isomerisation of boryl-substituted silole derivatives.
Bis(alkynyl)silanes (1a,b) react with bis(pentafluorophenyl)-borane to 3-boryl-2,5-bis(trimethylsilyl) substituted siloles 3a,b. Subsequent irradiation of 3 with Pyrex filtered UV light resulted in the complete conversion to the new 5-boryl-2,3-bis(trimethylsilyl) substituted siloles 4a,b.
