Addition of grignard reagents to aryl acid chlorides: an efficient synthesis of aryl ketones.
[chemical reaction: see text]. Direct addition of Grignard reagents to acid chlorides in the presence of bis[2-(N,N-dimethylamino)ethyl] ether proceeds selectively to provide aryl ketones in high yields. A possible tridentate interaction between Grignard reagents and bis[2-(N,N-dimethylamino)ethyl] ether moderates the reactivity of Grignard reagents, preventing the newly formed ketones from nuc...
متن کاملDi-Grignard reagents and metallacycles
Aliphatic ,w-dibromides can be converted to the corresponding c,w-di—Grignard reagents; for those members carrying less than four carbon atoms between the functions, special procedures are required. The synthesis, structure and applications of the di-Grignard reagents are discussed; particular emphasis is placed on the structures of the corresponding cyclic dialkylmagnesiums, and on the use of ...
متن کاملBoryl (Hetero)aryne Precursors as Versatile Arylation Reagents: Synthesis through C–H Activation and Orthogonal Reactivity
(Pinacolato)boryl ortho-silyl(hetero)aryl triflates are presented as a new class of building blocks for arylation. They demonstrate unique versatility by delivering boronate or (hetero)aryne reactivity chemoselectively in a broad range of transformations. This approach enables the unprecedented postfunctionalization of fluoride-activated (hetero)aryne precursors, for example, as substrates in t...

Thermal epimerization of diastereomeric Grignard reagents.
Thermal epimerization is the key to changing the endo-to-exo ratio of the diastereomeric bornyl and fenchyl Grignard reagents from 67:33 to 96:4 and from 20:80 to 80:20, respectively.
