Abstract
Abstract Dibenzimidazo crown ethers were synthesized by alkylation of α, ω-bis (benzimidazol-2-yl) alkanes and 1, 2-bis (benzimidazol-2-ylsulfanyl) ethane with tri-and tetraethylene glycol bis (4-toluenesulfonates). The structure of 6, 7, 9, 10, 12, 13, 21, 22- octahydro [1, 14, 6, 9, 4, 11] dioxadithiadiazacyclohexadecino [4, 5-a: 11, 10-a′] dibenzimidazole was studied by X-ray analysis.
