  由腈模板引导的 Rh(III)-催化的间位 C-H 烯烃化

  摘要：

  已经开发了一系列 Rh(III) 催化的邻位 CH 功能化；然而，这种反应性通过大环铑环中间体扩展到远程 CH 官能化尚未得到证实。在此，我们报告了使用 U 形腈模板通过假定的 12 元大环中间体指导 Rh(III) 催化的远程间位 CH 活化的第一个例子。由于用于 Rh(III) 催化剂的配体与 Pd(II) 催化剂的配体明显不同，这为配体促进的间位 CH 活化反应的未来发展提供了新的机会。

  On the generation and characterization of the spiro[2,5]octadienyl anion in the gas phase

  摘要：

  AbstractThree routes have been explored in both a high‐pressure chemical ionization (CI) source and a low‐pressure Fourier transform ion cyclotron resonance (FT‐ICR) cell to generate the spiro[2,5]octadienyl anion in the gas phase: (i) proton abstraction from spiro[2,5]octa‐4,6‐diene; (ii) expulsion of trimethysilyl fluoride by phenyl ring participation following fluoride anion attack upon the silicon centre of 2‐phenylethyl trimethylsilane; and (iii) collisionally induced dissociation (CID) of the carboxylate anion of 3‐phenylpropanoic acid via carbon dioxide loss. From comparison of the CID spectra of various reference [C8H9]− ions with those of the [C8H9]− ions which could be generated via the routes (i) and (iii) in the CI source it can be concluded that only the third route yields a [C8H9]−ion whose CID spectrum is not inconsistent with the one expected for the spiro[2,5]octadienyl anion. In the FT‐ICR cell [C8H9]− ions are generated along all three routes; their structures have been identified by specific ion‐molecule reactions and appear to be different. Route (i) yields an α‐methyl benzyl anion, probably due to isomerization within the ion‐molecule complex formed. An ortho‐ethylphenyl anion is formed along route (ii), presumably due to an intramolecular ortho proton abstraction in the generated trimethylsilyl fluoride solvated 2‐phenylethyl primary carbanion. The [C8H9]− ion formed along route (iii) shows reactions similar to those of the 1,1‐dimethylcyclohexadienyl anion which is structurally related to the spiro[2,5]octadienyl anion. Furthermore, the [C8H9]− ion generated via route (iii) reacts with hexafluorobenzene under expulsion of only one hydrogen fluoride molecule which contains exclusively one of the original phenyl ring hydrogen atoms. On the basis of all these observations it is therefore quite likely that the spiro[2,5]octadienyl anion is formed by collisionally induced decarboxylation of the 3‐phenylpropanoic acid carboxylate anion and can be a long‐lived and stable species in the gas phase.

Herein we report the first example of the use of a U-shaped nitrile template to direct Rh(III)-catalyzed remote meta-C-H activation via a postulated 12-membered macrocyclic intermediate. Because the ligands used for Rh(III) catalysts are
