Cyclohexano-15-crown-5, cyclohexano-18-crown-6, dicyclohexano-15-crown-5, and dicyclohexano-18-crown-6, but not dicylohexano-16-crown-5, in THF dissolve potassium metal to form dark blue potassium alkalide solutions at ambient temperature. On standing, the potassium alkalide complexes decompose and the solutions turn colorless at differing rates. Identification of the products provides insight into the decomposition mechanism.

A series of trans-cyclohexanocrown ethers were synthesized by the intermolecular cyclization of polyethylene glycol trans-2-hydroxycyclohexyl ethers with the ditosyl derivatives of polyethylene glycols.A complete assignment of the signals in the (13)C NMR spectra was made for the obtained compounds.
