General Description

1,3-Epoxy-3-methylbutane, also known as 3,4-Epoxypentane, is a chemical compound with the molecular formula C6H12O. It is a colorless liquid with a faint, sweet odor, and is commonly used as a reactive intermediate in the production of various chemicals, including adhesives, resins, and coatings. 1,3-Epoxy-3-methylbutane is highly flammable and may be harmful if inhaled, ingested, or absorbed through the skin, potentially causing irritation to the respiratory system and skin. It is important to handle this chemical with care and follow proper safety protocols when working with it.

Regiochemical Control in the Reductive Cleavage of 2-Alkylated Oxetanes by Use of Trialkylaluminums. Tertiary Organolithiums with γ-Oxy Functionality

Whereas 2,2-dialkylated oxetanes are cleaved by lithium 4,4'-di-tert-butylbiphenylide to provide the primary organolithium-tertiary oxyanions, the same reaction in the presence of trialkylaluminums gives exclusively the 3-lithio-3,3-disubstituted propoxides, which are trapped by carbonyl compounds in moderate yields.

Reactions of Methyl Radicals with 3-Methyloxetane, 3,3-Dimethyloxetane and 2,2-Dimethyloxetane

The reactions of methyl radicals with 3-methyloxetane, 3,3-dimethyloxetane and 2,2-dimethyloxetane have been studied.The overall rates of hydrogen-atom abstraction from these three compounds have been obtained over the temperature range 100-200 deg C by assuming the value of Quinn and coworkers (J.Chem.Soc.Faraday Trans.I, 1976, 72, 1935) for the rate of recombination of methyl radicals.The following rate expressions were found: log10(k4/cm3mol-1s-1)(30x) = 11.69 (+/-0.20)-38.23 (+/-0.84) kJmol-1/2.303RT, log10(k4/cm3mol-1s-1)(3,30x) = 11.72 (+/-0.20)-39.47 (+/-1.0) kJmol-1/2.303RT, log10(k4/cm3mol-1s-1)(2,20x) = 11.99 (+/-0.23)-41.24 (+/-1.13) kJmol-1/2.303RT.From these rate expressions and those obtained previously for three other oxetane molecules, the rate parameters for hydrogen-atom abstraction from five distinct sites in the substituted oxetane molecules have been obtained.
