%X Experimentally convenient syntheses of a series of gold(I) acetylide complexes containing tertiary phosphines include reactions between AuCl(PR3) [R3 = Me3, Ph3, Ph(OMe)2] and alk-1-ynes, either in diethylamine in the presence of copper(I) halides, or with methanol/sodium methoxide. Yields are good to excellent; several compounds are light-sensitive, and react violently with chlorinated solvents. The crystal structure of Au(C2C6F5)(PPh3) has been determined. It is monomeric, with almost linear two-coordinate Au: Au-C 1.993(14), Au-P 2.274(3), C=C 1.197(16) Å. Crystals are monoclinic, space group P21/c, with a 16.104(2), b 8,653(1), c 17.560(3) Å, &#946; 112.98(1)º, Z 4; 1761 data with I > 2.5&#963;(I) were refined to R, Rw = 0.033, 0.034.
