詳細
Potassium tert-butoxide is a strong alkoxide base, it can deprotonate carbon and other Brφnsted acids. It is a relatively poor nucleophile.
アプリケーション
Potassium tert-butoxide has been used as a strong base in the enantioselective synthesis of amines by transfer hydrogenation of N-(tertbutylsulfinyl)imines. It can also be used: To synthesize aliphatic and aromatic amides from corresponding esters and amines. As a base in the intramolecular cyclization of aryl ethers, amines, and amides. As a catalyst to prepare styrene derivatives from aryl halides and alkenes by Mizoroki-Heck reaction.

N-heterocyclic carbenes (NHCs) have emerged as a unique molecular platform for the formation of self-assembled monolayers (SAMs) on various surfaces. However, active carbene formation requires deprotonation of imidazolium salt precursors, which is mostly facilitated by exposure of the salt to

The direct functionalization of C-H bonds has drawn the attention of chemists for almost a century. C-H activation has mainly been achieved through four metal-mediated pathways: oxidative addition, electrophilic substitution, σ-bond metathesis and metal-associated carbene/nitrene/oxo insertion. However, the identification of

High-throughput experimentation (HTE) methods are central to modern medicinal chemistry. While many HTE approaches to C-N and Csp2 -Csp2 bonds are available, options for Csp2 -Csp3 bonds are limited. We report here how the adaptation of nickel-catalyzed cross-electrophile coupling of
