1,3-Dipolar cycloaddition of cyanopyridines to heterocyclic N-imines – combined experimental and theoretical studies

Autor: Vyacheslav G. Shubin, G. I. Borodkin, R. V. Andreev, Aleksey Yu. Vorob’ev

Series of 2-pyridyl substituted [1,2,4]triazolo[1,5-a]azines have been synthesized by reaction of cyanopyridines with N-aminoazinium mesitylenesulfonates under basic conditions. The reaction proceeds smoothly with pyridinium, 1,10-phenanthrolinium an

Exploratory study of the reaction of bis(2-methoxyethyl)aminosulfur trifluoride (Deoxofluor™ reagent) with diaryl sulfoxides: novel routes to Ar2SF2 and Ar2SF(OTf) via sulfoxide activation

Publikováno v: Journal of Fluorine Chemistry. 115:169-173

Neither bis(2-methoxyethyl)aminosulfur trifluoride (Deoxofluor™ reagent) nor HF/pyridine alone can fluorinate diaryl sulfoxides. S-fluorination can be effected by activating the sulfoxide via protonation with HF/pyridine (70:30) to form sulfoxonium

First application of ionic liquids in electrophilic fluorination of arenes; Selectfluor™ (F-TEDA-BF4) for 'green' fluorination

Autor: Kenneth K. Laali, G. I. Borodkin

Publikováno v: Journal of the Chemical Society, Perkin Transactions 2. :953-957

The NF fluorinating agent F-TEDA-BF4 dication salt (Selectfluor™) 1 dissolves in imidazolium-based ionic liquids [emim][OTf] 7, [emim][BF4] 8, [bmim][PF6] 9 and [bmim][BF4] 10 (assisted by sonication), providing a convenient medium for fluorination

Electrophilic reactivity and π-complexation studies in 1,8-naphthylene-bridged [3.2]paracyclophane with a cyclobutane calliper

Autor: Yosuke Nakamura, G. I. Borodkin, Takao Okazaki, Jun Nishimura, Kenneth K. Laali, Yoshitou Hayashida

Publikováno v: Journal of the Chemical Society, Perkin Transactions 2. :2347-2350

The 1,8-naphthylene-bridged [3.2]paracyclophane 1, a novel syn-paracyclophane which is further rigidified via a cyclobutane calliper, reacts with 2.2 equivalents of Br2 in CCl4 in the dark to give the symmetrical dibromo derivative 2. Bromination wit
