  金(I)配合物催化炔基亚砜的重排

  摘要：

  报道了一系列金 (I) 催化的炔基亚砜重排反应。高炔丙基亚砜重排为苯并噻吩酮或苯并噻吩，而α-硫烯酮在炔丙基亚砜的反应中形成。所提出的机制是通过金促进的氧原子从亚砜转移到炔烃形成的 α-羰基金-类胡萝卜素中间体进行的。

• Rearrangement of Alkynyl Sulfoxides Catalyzed by Gold(I) Complexes

  DOI：10.1021/ja070789e

  日期：2007.4.1

  A series of gold(I)-catalyzed rearrangement reactions of alkynyl sulfoxides are reported. Homopropargylsulfoxides are rearranged to benzothiepinones or benzothiopines, while α-thioenones are formed in the reaction of propargylsulfoxides. The proposed mechanism proceeds via an α-carbonyl gold−carbenoid intermediate formed through gold-promoted oxygen atom transfer from the sulfoxide to the alkyne.

• Exploring the Scope of Nitrogen Acyclic Carbenes (NACs) in Gold-Catalyzed Reactions

  The catalytic activity of the recently reported nitrogen acyclic carbene (NAG) complexes of gold(I) has been investigated and compared with the reported activity of other gold(I) and gold(III) complexes. The complexes studied, [AuClC(NEt2)(NHTol-p)}], [AuClC(NEt2)(NHXylyl)}], and [Au(NTf2)C(NEt2)(NHXylyl)}], are very active in processes such as the rearrangement of homo-propargylsulfoxides, the intramolecular hydroamination of N-allenyl carbamates, the intramolecular hydroalkoxylation of allenes, the hydroarylation of acetylenecarboxylic acid ester, and the benzylation of anisole. Although the NAG ligands have not been optimized for the reactions tested, the yields obtained are usually similar and sometimes better than those reported with other catalysts, showing that the presence of N-H bonds and the wider N-C-N angle in the NAG (as compared to the NHC) complexes are not detrimental for the catalysis. For the hydroarylation reaction (where two competing products can be formed), the NAG complexes allow favoring one over the other. For the benzylation of anisole the selectivity is complementary to that obtained using H[AuCl4] as catalyst, and depending on the substrate, the NAG gold(III) complexes outperform the activity of H[AuCl4]. On average, the reactivity found suggests that the basicity of NACs toward gold(I) is very similar to that of NHCs and higher than that of phosphines.
