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.

Modular One‐Pot Access to π‐Expanded Tetrakis(Phenothiazinyl)‐Silanes With Broadly Tunable Redox and Emission Properties

Chemistry – A European Journal, EarlyView.
A library of 21 tetrakis(phenothiazinyl)‐substituted silanes with broadly variable substituent decoration, which are fully reversible multistage redox systems with intense tunable emission from deep blue to yellow–green (441–533 nm), was rapidly synthesized by bromine–lithium exchange/borylation–Suzuki coupling of tetrakis(4‐bromophenyl)silane or by ...

Cyclopropylamine‐Derived Distonic Iminium Radicals: Photoinduced Strategies in Chemo‐ and Stereo‐Selective Synthesis

Chemistry – A European Journal, EarlyView.
Cyclopropylamines have emerged as powerful photocatalytic building blocks. Upon light‐induced single‐electron oxidation, they undergo strain‐release ring opening to generate distonic iminium radicals that enable diverse transformations, including ring‐opening functionalization, formal [3 + 2] cycloadditions, radical cascades, and asymmetric bond ...

Syntheses and Properties of Pentafluoroethylplumbanes in the Oxidation States +II, +III, and +IV

Chemistry – A European Journal, EarlyView.
Syntheses of pentafluoroethyl substituted plumbanes in the formal oxidation states +II, +III, and +IV are reported. The compounds were characterized by multinuclear NMR spectroscopy, including 207Pb NMR spectroscopy, mass spectrometry and single‐crystal x‐ray diffraction experiments. ABSTRACT Mono‐, bis‐, and tris(pentafluoroethyl)plumbanes of the type

RhodaMal Dyes: Novel Red Emissive Fluorophores as Probes for High Contrast Live‐Cell Imaging

Chemistry – A European Journal, EarlyView.
Incorporation of malononitrile into the traditional rhodol framework furnishes RhodaMal (Rhoda = Rhodamine, Mal = Malononitrile;) dyes, a new class of red emissive push–pull chromophores. Conjugating them to triphenylphosphonium cation enables live cell super‐resolution STED microscopy with a 775 nm depletion laser.
