carbon donor ligands results in reductiveelimination. Combined experimental and computational investigations lead to the first evidence of a direct intramolecular C(sp2)–N(sp2) bond formation from a monomeric [(C^N)AuCl2] gold(III) complex. We show that bidentate ligated Au(III) systems bypass transmetallation to form C(sp2)–N(sp2) species and NHC–Au–Cl. Mechanistic investigations of the reported transformation

A compound of formula (I): which inhibits the activity of one or more KATs of the MYST family, i.e., TIP60, KAT6B, MOZ, HBO1 and MOF.
The development of a sequential O–H/C–Hbond functionalization of phenols initiated by the cationic gold(I)-catalyzed cyclization of 1-bromo-1,5-enynes to produce (2-bromocyclopent-2-en-1-yl)phenols is reported. This unprecedented domino transformation efficiently proceeds under mild conditions (5 mol % of (t-Bu)3PAuNTf2, CH2Cl2, 0–23 °C) via an intermediate aryl alkyl ether which collapses at ambient

Nucleophilic terminal gold(I) amides have been prepared and their reactivity toward a variety of electrophiles has been explored. For the first time these frequently proposed intermediates were isolated and shown to be unreactive in the amination of π-bonds. The first crystallographically determined terminal group 11 metal phosphide was also synthesized. Preliminary DFT studies have been conducted

we report on the photoredox-initiated gold-mediated C(sp2)-CF3 and C(sp2)-N coupling reactions. By adopting gold as a platform for probing metallaphotoredox catalysis, we demonstrate that cationic gold(III) complexes are the key intermediates of the C-C and C-N coupling reactions. The high-valent gold(III) intermediates are accessed by virtue of photoredox catalysis through a radical chain process. In
在此,我们报告了光氧化还原引发的金介导的 C(sp2)-CF3 和 C(sp2)-N 偶联反应。通过采用金作为探测金属光氧化还原催化的平台,我们证明了阳离子金 (III) 配合物是 CC 和 CN 偶联反应的关键中间体。高价金 (III) 中间体通过自由基链过程通过光氧化还原催化获得。此外,偶联反应的键形成步骤是阳离子金 (III) 中间体的还原消除,这得到了关键 Au (III) 中间体的分离和晶体学表征的支持。
