A data-driven and quantum chemistry-anchored framework for modeling and classifying carbon–lithium bonding in organolithium aggregates

We present a quantum chemistry-based, data-driven framework for the automated classification of carbon–lithium bonding motifs in archetypal organolithium aggregates. Starting from …

A Precise Synthetic Toolbox: H-Bond-Assisted Quadruple Reactivity of o-Dimethylaminoaryloximes

It has been shown that azomethines, hydrazones, and oximes derived from 2(7)-carbonyl derivatives of 1,8-bis(dimethylamino)naphthalene can undergo acid-catalyzed heterocyclization …

«Buttressing Effect» in the Halogen-Lithium Exchange in ortho-Bromo-N,N-dimethylanilines and Related Naphthalenes

Non-covalent interactions such as coordination of an organolithium reagent by a directing group and steric repulsion of substituents strongly affect the halogen-lithium exchange …
