Explosive gold acetylide has been known since the mid-nineteenth century, but systematic studies of this type of compounds were initiated by Coates in 1959. The early work on gold carbonyls dates back to 1925, when Manchot discovered (OC)AuCl, while the related isocyanide complexes were prepared only in 1956 by Sacco. Gold-carbene... 

Low solubilities are a major problem that commonly occurs in the preparation of metal-containing acetylide polymers. Puddephatt and co-workers found that altering the phosphine ligands around the Au centers could control the solubility of gold acetylide polymers.34,57,58,59 Polymer 14 possessed molecular weights estimated to range between 13,700 and 27,000.23... 

Alkynylgold(I) hahde anion complexes have been prepared from suitable gold acetylide precursors by addition of hahde ion, as illustrated in equation 1770, or reacting a bis(acetyhde)aurate(I) with a dihalogenoaurate(I) (equation 18)76. 

Luminescent gold(I) acetylides (74-76) with a rigid rod-like structure have been synthesized. Their photochemical and photophysical properties have been studied in some detail155. The emission properties of the gold acetylides 77 have been studied. This... 

Yam and co-workers have investigated cation receptors based on gold-acetylide complexes. For instance, calix[4]crown 47 functions as a colorimetric sensor for Na and K. UVA IS spectrophotometric titration of 47 in GH2CI2/CH3OH (1/1) solution with these cations determined a 1 1 binding stoichiometry in each case and stability constants of 1.74 x 10 and 5.62 x 10 for the 47 and 47 Na species, respectively. This is a...
