《Oxidative C-H/C-H Annulation of Imidazopyridines and Indazoles through Rhodium-Catalyzed Vinylene Transfer》 was written by Ghosh, Koushik; Nishii, Yuji; Miura, Masahiro. Recommanded Product: Vinylene carbonate And the article was included in Organic Letters in 2020. The article conveys some information:
In the presence of [Cp*Rh(MeCN)3](SbF6)2 in 1,2-dichloroethane, 2-arylimidazo[1,2-a]pyridines, 2-arylindazoles, arylpyrazolopyridines, and an arylimidazobenzothiazole underwent cyclocondensation reactions with vinylene carbonate to yield naphthoimidazopyridines such as I, quinolinoindazoles such as II, benzopyridoindazoles such as III, and a naphthoimidazobenzothiazole. The UV/visible and fluorescence spectra of I, II, and III were obtained and their solution and solid-state fluorescence quantum yields determined In the experiment, the researchers used Vinylene carbonate(cas: 872-36-6Recommanded Product: Vinylene carbonate)
Vinylene carbonate(cas: 872-36-6) belongs to esters. Alkyl carbonates find applications as solvents for lithium ion battery electrolytes and the use of high quality battery grade electrolytes having extremely low water (<10 ppm) and acid (<10 ppm) contents are critical for achieving high electrochemical performance.Recommanded Product: Vinylene carbonate
