On July 1, 2022, Zhao, Lanxiao; Deng, Peng; Gong, Xun; Kang, Xiaohui; Cheng, Jianhua published an article.Name: 2-Methoxynaphthalene The title of the article was Regioselective C-H Alkylation of Aromatic Ethers with Alkenes by a Half-Sandwich Calcium Catalyst. And the article contained the following:
The catalytic ortho-regioselective C-H alkylation of a of alkoxy-substituted benzene derivatives with alkenes could be achieved by the use of a half-sandwich calcium alkyl complex [(CpAr5)Ca{CH(SiMe3)2}(THF)] (CpAr5 = C5Ar5, Ar = 3,5-i-Pr-C6H3) as the precatalyst to form 1-alkoxy-2-phenethylbenzene derivatives I [R = H, 4-Me, 4-SMe, etc.; R1 = OMe, OEt, i-Pr, etc.]. The potential catalytic reaction intermediates, half-sandwich calcium anisyl complexes [(CpAr5)Ca(o-MeO-m-Ph-C6H3) (THF)2] and [(CpAr5)Ca(o-MeO-2-Np) (THF)2] (Np = naphthyl), were isolated and X-ray structurally characterized. DFT calculations were carried out to elucidate the different reaction profiles of sp2 and sp3 C-H activations. The experimental process involved the reaction of 2-Methoxynaphthalene(cas: 93-04-9).Name: 2-Methoxynaphthalene
