Unlocking Structural Diversity in Gold(III) Hydrides: Unexpected Interplay of cis/ trans-Influence on Stability, Insertion Chemistry, and NMR Chemical Shifts.

ABSTRACT: The synthesis of new families of stable or at least spectroscopically observable gold(III) hydride complexes is reported, including anionic cis-hydrido chloride, hydrido aryl, and cis-dihydride complexes. Reactions between (C^C)AuCl(PR₃) and LiHBEt₃ afford the first examples of gold(III) phosphino hydrides (C^C)AuH(PR₃) (R = Me, Ph, p-tolyl; C^C = 4,4'-di- tert-butylbiphenyl-2,2'-diyl). The X-ray structure of (C^C)AuH(PMe₃) was determined. LiHBEt₃ reacts with (C^C)AuCl(py) to give [(C^C)Au(H)Cl]^-, whereas (C^C)AuH(PR₃) undergoes phosphine displacement, generating the dihydride [(C^C)AuH₂]^-. Monohydrido complexes hydroaurate dimethylacetylene dicarboxylate to give Z-vinyls. (C^N^C)Au pincer co
