For 10 points, name these organic compounds with two R groups bonded to an oxygen atom, whose diethyl type is a solvent and anesthetic.
Grignard reagents can be dissolved in one of these, THF, and a five-membered aromatic one is called furan. Compounds of this type with a triangular ring are called epoxides. Phase transfer catalysis makes use of one oligo·mer·ic type which forms coordination complexes. Their synthesis occurs in an SN2 reaction of an alkoxide ion with an alkyl halide. With a ring-shaped "crown" type, their synthesis reaction is named after Williamson.
