Cyclodeca-1,3-dien-5-yn1-yl trifluoromethanesulphonate (2) has been synthesized and solvolysed in different solvent systems to give cyclized aromatic products exclusively, which are formed mainly via an aryl cation (5) intermediate.

Ni complexes with N4-donor aminopyridine ligands efficiently catalyze regioselective oxidation of organic substrates at benzylic C−H groups. Crucially, using trifluoroethanol as reaction solvent diverts the reaction selectivity towards 1-phenylalkyl 2,2,2-trifluoroethyl ethers in high yields.
Ni 与N 4-供体氨基吡啶配体的配合物可有效催化有机底物在苄基 C−H 基团上的区域选择性氧化。至关重要的是,使用三氟乙醇作为反应溶剂可以将反应选择性转向 1-苯基烷基 2,2,2-三氟乙基醚,且产率较高。
