This functional group is present in the polar solvent tetrahydrofuran.
An allyl vinyl form of these compounds can undergo the Claisen rearrangement. This functional group is present in the polar solvent tetrahydrofuran. Tert-butyl hydroperoxide and an alcohol containing a double bond react to create these compounds in the Sharpless epoxidation. The aforementioned reaction creates epoxides, cyclic forms of this group. The Williamson reaction creates one of these compounds from an alcohol and an organohalide, and these groups connected in a ring form the "crown" type. A diethyl form of this functional group serves as an anesthetic. For 10 points, name these compounds that consist of an oxygen bonded to two alkyl or aryl groups.
An allyl vinyl form of these compounds can undergo the Claisen rearrangement.
