β-Methoxy alcohols are easily obtained from the one-pot reaction of alkenes with oxone in methanol, in the absence of any additive or catalyst. The use of other alcohols as solvents has shown that the efficiency of the process decreases with the steric hindrance of the alcohol.

The synthesis of a new type of lanthanide alkoxides is described.The "clinching alcohols" HOCHtBuCH2OEt (1a), HOCHtBuCH2NEt2 (1b), HOCtBu2CH2OEt (1c), and HOCHiPr2CH2OEt (1d) react with Nd2>3 (2a) to form the corresponding homoleptic alkoxide complexes 3a-d.The same procedure is applied to obtain the novel yttrium alkoxide 4 from the amide precursor 2b and the alcohol 1d.The new complexes are all very soluble in aliphatic hydrocarbons and were characterized by means of analyses and spectroscopy.The interesting property of these complexes is their remarkable volatility, the highest so far achieved for lanthanide alkoxides.Key Words: Neodymium complexes / Yttrium complexes / Alkoxides, functionalized / Volatility / NMR, 89Y

The nature and the stereoisomeric distribution of the neutral products obtained from the gas-phase attack of radiolytically formed Broensted +, CH5+, C2H5+, and t-C4H9+> and Lewis +, t-C4H9+, and CH3FCH3+> acids on several substituted 1,2-epoxycyclohexanes have been investigated under different experimental conditions.Isolation and identification of the neutral substituted products allowed us to confirm previous indications about highly regio- and stereo-selective cationic nucleophilic displacements on these substrates occuring in the gas-phase with complete inversion of the configuration at the reaction centre (the α-C atom).In some cases, extensive acid-induced isomerization became the only observable pathway.The relative extent of the competiting substitution and isomerization was found to depend on several factors, including the structural features and internal energy of the oxonium derivative of the epoxy substrate.The results obtained from the present gas-phase experiments are discussed in relation to gas-phase and solution studies.
