3,3,6,6-Tetramethyl-1-thiacyclohept-4-yne-1,1-dioxide, abbr. SO2-alkyne (2), reacts with the copper(I) halides CuCl, CuBr, CuI to form the dinuclear complexes [CuX(SO2-alkyne)]23a, 3b, and 3c, respectively. X-ray diffraction studies on all three compounds 3 exhibit a decrease in strength of the copper–alkyne bond when going from X=Cl (Cu–C 194.7 pm) to X=Br (Cu–C 196.7 pm) and X=I (Cu–C 198.6 pm).
