Abstract
Abstract Macrocyclic sulfides useful as complexing agents for ionic metal compounds and as dye intermediates are prepared, e.g., by the reaction of one or more carbocyclic nuclei having vicinal hydroxy or mercapto groups with a halogen-di-terminated alkylene, alkylene ether, alkylene thioether or alkylene ether thioether compound. The macrocyclic sulfides comprise a macrocyclic ring composed of oxygen and sulfur atoms separated one from the other by chains of from one to three carbon atoms, the ring having from 12 to 30 ring atoms and having fused thereto by vicinal carbon atoms from 1 to 4 cyclic aromatic hydrocarbons (e.g., benzene, naphthalene or cyclic nonaromatic hydrocarbons (e.g., cyclohexane, decalin).
