ALLYLATION REACTIONS OF CRESOLS WITH ALLYL ALCOHOL IN THE PRESENCE OF NANOCATALYSTS
Downloads
The allylation reactions of isomeric cresols with an allylating agent, allyl alcohol, and the influence of the catalyst nature on the reaction progress and yield were studied. The physical constants of allylcresols were determined. The structure was confirmed by IR and NMR spectroscopy data. The influence of solvents and temperature on the reaction progress was studied.
