Toward Chromoselective Transformations in Biological Systems: Perspectives and Challenges

Angewandte Chemie International Edition, EarlyView.
Controlling biological systems with small‐molecule chromophores has evolved into a powerful strategy and is applied from chemical biology to medicine. However, the complexity of in vivo systems cannot be matched by a single wavelength of light. Developing methods to combine and individually control multiple chromophores is crucial.

Broadband fluorescence reveals mechanistic differences in excited-state proton transfer to protic and aprotic solvents

, 2020
Excited-state proton transfer (ESPT) to solvent is often explained according to the two-step Eigen-Weller model including a contact ion pair (CIP*) as an intermediate, but general applicability of the model has not been thoroughly examined.

Prolonged Luminescence Lifetime of a Dual Emissive Ruthenium Dipyridophenazine-Type Complex in Aprotic and Protic Solvents

, 2021
A recently reported ruthenium­(II) complex bearing an extended dipyridophenazine ligand exhibits unusual long-lived dual emission at room temperature. In this study, the effect of the introduction of a methyl protecting group to the imidazole moiety of ...

PGSE and NOE NMR evidence for higher order aggregation in some cationic ruthenium complexes in both protic and aprotic solvents

, 2003
PGSE and NOE NMR measurements were carried out for complexes [Ru(eta(6)-cymene)((2-R-C6H4)N=C(Me)-C(Me)=N(2-R-C6H4))Cl]X (X=BF4 or BPh4) in both protic and aprotic solvents with a relative permettivity (epsilon(r)) ranging from 2.27 (benzene-d(6)) to 46 ...

Bromination of Alkenes and Related Compounds by Use of Benzyltrimethylammonium Tribromide in Aprotic and Protic Solvents

, 1988
The reaction of alkenes and related compounds (1) with benzyltrimethyl-ammonium tribromide (BTMA Br_3) in aprotic solvents such as dichloromethane and chloroform gave 1, 2-dibromo adducts in fairly good yields.

A Ruthenium‐(Ph‐BPE) Catalyst for Asymmetric Alkynylation of Fluoral: Enantioselection From 1 of 12 Fluxional Stereogenic‐at‐Ruthenium Complexes

Angewandte Chemie International Edition, EarlyView.
The first enantioselective alkynylations of aqueous fluoral are described. These processes are catalyzed by an iodide‐bound ruthenium‐(Ph‐BPE)‐catalyst; an octahedral metal complex that can exist as 12 diastereomeric‐at‐metal isomers. Calculations reveal that 2 of 12 stereoisomeric complexes account for 99.9% of the Boltzmann population and that ...
