FLP Mediated Conversion of Difluorobenzylalkynes to Fluoroallenyl Oniums via an SN1’ Pathway

Chemistry – A European Journal, EarlyView.
Frustrated Lewis pair (FLP) selective C‒F activation of difluorobenzylalkynes allows the formation of fluoroallenic oniums via an SN1’ substitution pathway. The fluoroallenic onium salts are synthetic precursors that allow subsequent functionalization at allenic and onium positions.

Nitrooxylation in Organic Synthesis: From Classical Nitrate Ester Formation to Modern Catalytic Strategies

Chemistry – A European Journal, EarlyView.
Nitrooxylation—the installation of nitrate esters (–ONO2) has evolved from classical mixed‐acid protocols to catalytic and mechano‐, flow‐, photo‐, and electrochemical strategies. This review delineates ionic and radical manifolds for C–ONO2 bond formation, emphasizing mechanistic control, selected substrate scope, and selectivity.

Stereochemical Control in the Matteson Reaction

Chemistry – A European Journal, EarlyView.
The Matteson homologation is a highly versatile method for the stereoselective insertion of carbenoids into boronic esters. Through iterative application of the process, complex chiral molecules can be synthesized. The stereoselectivity of the reaction is determined by a chiral diol incorporated in the boronic ester.

Tailoring Liquid Crystalline Self‐Assembly and Photophysical Properties of Unsymmetrical Fluorenones via Polar Terminal Groups

Chemistry – A European Journal, EarlyView.
Novel liquid crystalline fluorenones bearing various head groups were synthesized and characterized. By alteration of the head group, N, SmC, or SmA phases were obtained, and emission properties could be tuned depending on solvent or temperature. ABSTRACT In this work, a series of novel unsymmetrical fluorenone derivatives bearing various head groups ...
