TL;DR: In this paper, it was suggested that the oxidation occurred at the surface of the crystalline 2-naphthols via a solid-liquid process, which can be also effectively applied to the large-scale synthesis of 1, 1′ -bi-2 naphthol.

TL;DR: In this paper, a highly efficient and practical resolution of racemic 1,1′-bi-2-naphthol has been achieved through molecular complexation with N-benzylcinchoninium chloride, which can be readily prepared in 85% yield using an improved procedure through the reaction of cinchonine with benzyl chloride in dimethylformamide (DMF).

TL;DR: In this paper, a new method for optical resolution of racemic 1,1′-bi-2-naphthol (BINOL) has been developed through molecular complexation with a cheap and readily accessible (S)-5-oxopyrrolidine-2 carboxanilide, affording the enantioenriched BINOL in up to 70.4% ee and 73.6% yield.

Journal ArticleDOI
TL;DR: This work has reported several recently reported Cu-catalyzed C-H oxidation reactions that feature substrates that are electron-deficient or appear unlikely to undergo single-electron transfer to copper(II), and evidence has been obtained for the involvement of organocopper(III) intermediates in the reaction mechanism.
Abstract: The selective oxidation of C-H bonds and the use of O(2) as a stoichiometric oxidant represent two prominent challenges in organic chemistry. Copper(II) is a versatile oxidant, capable of promoting a wide range of oxidative coupling reactions initiated by single-electron transfer (SET) from electron-rich organic molecules. Many of these reactions can be rendered catalytic in Cu by employing molecular oxygen as a stoichiometric oxidant to regenerate the active copper(II) catalyst. Meanwhile, numerous other recently reported Cu-catalyzed C-H oxidation reactions feature substrates that are electron-deficient or appear unlikely to undergo single-electron transfer to copper(II). In some of these cases, evidence has been obtained for the involvement of organocopper(III) intermediates in the reaction mechanism. Organometallic C-H oxidation reactions of this type represent important new opportunities for the field of Cu-catalyzed aerobic oxidations.
