In presence of bismuth(III) triflate, a carbonylated electrophile (ethyl mesoxalate or glyoxylate) and usual diene led selectively (60-100) the hetero carbonyl-Diels-Alder reaction with the ene reaction product. Bi(OTf) 3 exhibits strong catalytic activity and reacts under mild conditions. En présence de triflate de bismuth(III) le mésoxalate et le glyoxylate d'éthyle réagissent avec des diènes usuels pour donner un mélange de carbonyl-Diels-Alder et du produit de la ène réaction. Bi(OTf) 3 présente une forte activité catalytique et réagit dans des conditions douces. 相似文献

Abstract The syntheses of organometallics such as alkyllithium compounds are performed. Furan and thiophene derivatives were prepared. Parameters which influence the yield have been optimized. The more important were the physical states of lithium and its sodium content and the nature of the substrate. 相似文献

When di-n-decylphosphonate 1a or di-benzylphosphite 1b are reacted with furan imine 2a or thiophenic imine 2b , the reaction leads to an f -aminophosphonate: 3a , 3b , or 3c following an ion- or radical-based reaction. 相似文献

Abstract Amidoximes (1) reacted with isopropenyl acetate in presence of KSF under microwave irradiation and gave 1,2,4-oxadiazoles (2). 1,2,4-Oxadiazoles (4) can also be obtained by microwave irradiation from O-acylamidoximes (3) adsorbed on Alumina. 1,3,4-Oxadiazoles (6) were obtained by irradiation of bis (acyl) hydrazines (5) in thionyl chloride. 相似文献
