The crownthioether 3 with the novel diisopropylidene building block was synthesized by an S′N cyclization reaction of 2,7-dichloro-2,7-dimethylocta-3,5-diyne (1) with 3-thia-pentane-1,5-dithiol (2). Ligand 3 shows all the sulfur centers in exodentate positions. Reaction of 3 with Ag1 triflate and triphenylphosphane yielded the tetrahedral complex 4, which shows unique spectroscopic data in solution

The reaction of 2,7-dimethyl-2,7-dichloroocta-3,5-diyne (1) with several alpha-omega-dithiols leads to crown thioethers with 1,4 diisopropylidene-2-butyne units as building
