Palladium-catalyzed Substitution Reaction of Allylic Derivatives with Tinacetylene.
The substitution reaction of allylic derivatives (acetate, carbonate, and chloride) with tinacetylene proceeded in the presence of palladium as a catalyst to give a product having a 1-ene-4-yne system.
متن کاملPd-catalyzed reaction of aryl halides and propargyl furylmethyl ethers: a novel pathway to functionalized dihydroisobenzofurans.
An interesting sequential reaction involving Sonogashira coupling, propargyl-allenyl isomerization, intramolecular [4 + 2] cycloaddition, and bridged oxa-ring opening has been realized, providing a facile method for the synthesis of functionalized dihydroisobenzofurans from easily accessible starting materials with a decent diastereoselectivity.
متن کاملthe evaluation of language related engagment and task related engagment with the purpose of investigating the effect of metatalk and task typology
abstract while task-based instruction is considered as the most effective way to learn a language in the related literature, it is oversimplified on various grounds. different variables may affect how students are engaged with not only the language but also with the task itself. the present study was conducted to investigate language and task related engagement on the basis of the task typolog...
15 صفحه اولA comparative study of the Au-catalyzed cyclization of hydroxy-substituted allylic alcohols and ethers
The Au(I)-catalyzed cyclization of hydroxyallylic ethers to form tetrahydropyrans is reported. Employing (acetonitrile)[(o-biphenyl)di-tert-butylphosphine]gold(I) hexafluoroantimonate, the cyclization reactions were complete within minutes to hours, depending on the substrate. The reaction progress was monitored by GC, and comparisons between substrates demonstrate that reactions of allylic alc...
