  The acceptorless dehydrogenative cross-coupling of primary alcohols to form cross-esters with the liberation of H2 gas was enabled using a [RuCl(η6-C6H6)(κ2-CNP)][PF6]Cl complex as the catalyst. This sustainable protocol is applicable to a broad range of primary alcohols, particularly for the sterically demanding ones, featuring good functional group tolerance and high selectivity. The good catalytic

  使用 [RuCl(η 6 -C 6 H 6 )(κ 2 -CNP)][PF 6 ]Cl 络合物，可以实现伯醇的无受体脱氢交叉偶联以形成交叉酯并释放 H 2气体催化剂。这种可持续的协议适用于广泛的伯醇，特别是对于空间要求高的伯醇，具有良好的官能团耐受性和高选择性。良好的催化性能可归因于氮-膦功能化的N-杂环卡宾（CNP）配体，它采用面配位模式以及配位苯的容易解离。

• The effect of<i>para</i>-substitution on the mass spectra of arylsulphonate esters of neopentanol
  作者：Orval A. Mamer、Abeysinghe A. Padmapriya、George Just

  DOI：10.1002/oms.1210201210

  日期：1985.12

  AbstractThe mass spectra of several para‐substituted benzenesulfonic and benzoic esters of unlabelled and 1,1‐d2‐neopentyl alcohol are examined and compared. Evidence is presented of migration of the aryl group from the sulfur to an oxygen atom in the molecular ions of the sulfonic esters. The nature of the fragmentation processes and the occurrence of metastable ions for these processes are both much more dependent upon the polarity of the para substituent in the case of the sulfonates than for the benzoates. Elimination of C5H10 occurs from the molecular ion of the p‐methoxysulfonate with transfer to the residual ion of a hydrogen atom selected randomly from the alkyl fragment, while in the case of the p‐aminosulfonate, incomplete randomization is demonstrated.
