Treatment of tetraphenyldistibine (1) with terminal arylacetylenes, XC6H5C equivalent to CH (2a-c, X = H, F, OMe), gave the corresponding anti-addition products (E)-aryl-1,2-bis(diphenylstibyBethenes 3a-c in 11-17 % yields. A similar reaction of 1 with 1,4-diphenylbutadiyne provided (E)-1,4-diphenyl-1,2-bis(diphenylstibyl)but- 1-en-3-yne (3d) in 28% yield. X-Ray diffraction studies on crystals of 3a, 3b and 3d revealed a congested configuration around the ethylene core. The optical properties of the adducts 3a-d were examined by measuring UV absorption and photoluminescence spectra. Interestingly, 3d showed phosphorescence in the solid state, which was enhanced at low temperature.
