  Regioselective synthesis of benzazetines and indoles from o-alkenylanilides was achieved. The reaction of o-vinylbenzanilide with dimethyl(methylthio)sulfonium trifluoromethanesulfonate (DMTST) gave the corresponding benzazetine in 92% yield, whereas the reaction of o-vinyl-N-p-toluenesulfonylanilide gave N-tosylindoline in 77% yield. 3-Methy-N-p-tosylindole was directly synthesized by the reaction of o-isopropenyl-N-p-tosylanilide with dimethyl disulfide and methyl triflate in 85% yield.

  is an unusual Cp*CyRh(III)-catalyzed intramolecular site-specific aryl C–H annulation, a highly chemoselective protocol providing direct access to eight-membered sultams/lactams with broad substrate/functional group tolerance. Experimental and computational studies reveal that such a transformation involves a unique PivOH-assisted aryl C–H activation/alkene insertion/β-H elimination/hydrogen-transfer

  A RhIII complex featuring an electron‐deficient η5‐cyclopentadienyl ligand catalyzed an unusual annulation between alkynes and 2‐alkenyl anilides to form synthetically appealing 2‐substituted indolines. Formally, the process can be viewed as an allylic amination with concomitant hydrocarbonation of the alkyne. Mechanistic experiments indicate that this transformation involves an unusual rhodium migration

  Low-valent cobalt complexes can promote intramolecular (3 + 2) cycloadditions of alkyne-tethered cyclopropenes to provide bicyclic systems containing highly substituted cyclopentadienyl moieties with electronically diverse functional groups. The adducts can be easily transformed into new types of CpRh(III) and CpIr(III) complexes, which show catalytic activity in several relevant transformations. Preliminary

  低价钴配合物可以促进炔系环丙烯的分子内（3 + 2）环加成，以提供含有高度取代的环戊二烯基部分和电子多样化官能团的双环系统。该加合物可以很容易地转化为新型的 CpRh(III) 和 CpIr(III) 配合物，在一些相关的转化中表现出催化活性。初步计算（DFT）和实验研究提供了有关钴催化过程的机械特性的相关信息，并使我们能够合理化其相对于同系铑促进反应的优势。
• Palladium-Catalyzed Formal (5 + 2) Annulation between <i>ortho</i>-Alkenylanilides and Allenes

  2-Alkenyltriflylanilides react with allenes upon treatment with catalytic amounts of Pd(OAc)(2) and Cu(II) to give highly valuable: 2,3-dihydro-1H-benzo[b]azepines, in good yields, and with very high regio- and diastereoselectivities. Density functional theory (DFT) calculations suggest that the C-H activation of the alkenylanilide involves a classical concerted metalation-deprotonation (CMD) mechanism.
