The chemical equilibrium of the reactive systems (alkanol + methylbutenes ? alkyl tert-amyl ether) with the following alkyl substituents: ethyl, propyl, butyl, iso-propyl, sec-butyl, and cyclohexyl, were studied in the liquid phase. Reactions were investigated in the screwed vials in the temperature range (298 to 393) K, and a cation exchanger Amberlist 15 was used as heterogeneous catalyst. Enthalpies of reactions ΔrH m° of teri-amyl alkyl ethers synthesis in the liquid phase were obtained from the temperature dependence of the equilibrium constants and used to derive standard enthalpies of formation, ΔfH m°(1), of tert-amyl alkyl ethers. For the sake of comparison, these enthalpies of formation have been calculated using improved Benson's increments. Calculated values are in close agreement with those from thermochemical measurements.

Allyl alcohols and ethers were readily hydroaluminated by LiAlH4 in the presence of zirconium compounds to give organoaluminum compounds in which the aluminum atom is placed at the terminal position of the substrate.ZrCl4 was the most effective catalyst for hydroalumination of allyl alcohols, whilst Cp2ZrCl2 was more effective than ZrCl4 for allyl ethers.
