Anion–π Catalysis Enabled by the Mechanical Bond**

چکیده
Abstract We report a series of rotaxane‐based anion–π catalysts in which the mechanical bond between bipyridine macrocycle and an axle containing NDI unit is intrinsic to activity observed, including [3]rotaxane that catalyses otherwise disfavoured Michael addition >60 fold selectivity over competing decarboxylation pathway dominates under Brønsted base conditions. The results are rationalized by detailed experimental investigations, electrochemical computational analysis.

Chemoselective Aliphatic C–H Bond Oxidation Enabled by Polarity Reversal
Methods for selective oxidation of aliphatic C-H bonds are called on to revolutionize organic synthesis by providing novel and more efficient paths. Realization of this goal requires the discovery of mechanisms that can alter in a predictable manner the innate reactivity of these bonds. Ideally, these mechanisms need to make oxidation of aliphatic C-H bonds, which are recognized as relatively i...

Strong and stable under tension? In this review we present the recent efforts investigating the mechanochemical properties of interlocked structures by atomic force microscopy and polymer mechanochemistry.
متن کاملMechanostereochemistry and the mechanical bond.
The chemistry of mechanically interlocked molecules (MIMs), in which two or more covalently linked components are held together by mechanical bonds, has led to the coining of the term mechanostereochemistry to describe a new field of chemistry that embraces many aspects of MIMs, including their syntheses, properties, topologies where relevant and functions where operative. During the rapid deve...

This section explains the design flow of the units described in figure S1. Once the prerequisites for the paths for the enzymatic action are determined, the design of the units is further constrained to represent the conformation change. We first designed the unit outline of S such that two combined units can represent a conformation change. The designed S, (SL and SS) can rotate through a rela...
متن کاملMechanical catalysis on the centimetre scale
Enzymes play important roles in catalysing biochemical transaction paths, acting as logical machines through the morphology of the processes. A key challenge in elucidating the nature of these systems, and for engineering manufacturing methods inspired by biochemical reactions, is to attain a comprehensive understanding of the stereochemical ground rules of enzymatic reactions. Here, we present...
