Carbon-gold bond formation through [3 + 2] cycloaddition reactions of gold(I) azides and terminal alkynes

Carbon-gold bond formation propels a growing number of homogeneous catalyses, but the C-Au bond formation itself is comparatively underinvestigated. Reported here are C-Au bond-forming reactions that result from [3 + 2] cycloaddition of (triphenylphosphine)gold(I) azide to terminal alkynes. The reaction proceeds with the preformed azide complex or, in situ, by reaction of the corresponding gold(I) alkynyl with trimethylsilyl azide in the presence of protic solvents. This metal-mediated cycloaddition is analogous to the Huisgen dipolar addition of azides and alkynes and provides access to new classes of gold-bearing compounds and materials.

Chemistry of the Group 1B Metals. XVII. Preparation of Some Gold(I) Acetylide Complexes Containing Group 5 Donor Ligands: Crystal and Molecular Structures of Au(C2C6F5)(PPh3)

Experimentally convenient syntheses of a series of gold(I) acetylide complexes containing tertiary phosphines include reactions between AuCl(PR3) 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(C2H6F5)(PPh3) has been determined.It is monomeric, with almost linear two-coordinate Au: Au-C 1.993(14), Au-P 2.274(3), CC 1.197(16) Angstroem.Crystals are monoclinic, space group P21/c, with a 16.104(2), b 8.653(1), c 17.560(3) Angstroem, β 112.98(1) deg, Z 4; 1761 data with I > 2.5?(I) were refined to R, Rw = 0.033, 0.034.
