Bifunctional Aziridines from Photochemically Generated FSO2NH2 for SuFEx Diversification of Alkenes
Angewandte Chemie, Volume 138, Issue 2, 9 January 2026.Photochemically generated FSO2NH2 serves as a safe, practical nitrene precursor for Rh‐catalyzed aziridination of alkenes, granting access to previously inaccessible fluorosulfonyl aziridines. These bifunctional electrophiles merge aziridine ring strain with SuFEx reactivity to provide a modular platform toward aliphatic sulfamoyl fluoride derivatives ...

Chiral thiols. Synthesis and enantiomeric excess determination
, 1987 Chiral thiols are a class of chira compounds, which is gaining mone and nore attention the last decenniun. Especially α-mercaptocarboxylic acids are frequently found as a structunal unit in (biologically) important products. As a consequence, many synthetic analoga or derivatives of these natural products, but also other organosulfur compounds, have ...

Chemistry – A European Journal, Volume 32, Issue 3, 16 January 2026.The design and synthesis of a linear tetradentate NCCN ligand incorporating two 1,2,3‐triazolin‐5‐ylidene mesoionic carbene donors, and its application to asymmetric iron catalysis is reported. This work represents the first example of an iron complex derived from a cis‐α‐coordinating tetradentate NCCN ligand, and notably, the first chiral iron ...

Synthesis of Enantiopure [3]Cyclorubicenes
Angewandte Chemie, Volume 138, Issue 1, 2 January 2026.Herein, we present a high yielding synthesis of enantiopure [3]cyclorubicene, which is a potential precursor for a Haeckelite nanotube. This macrocycle was studied for its electronic and chiroptical properties and exhibits one of the highest dissymmetry values reported for a nanohoop.

European Journal of Organic Chemistry, Volume 29, Issue 2, January 16, 2026.We synthesized a series of light to heavy fluorous Hoveyda–Grubbs precatalyst analogs modified in the alkoxybenzylidene part in positions 2 and 5 by long (fluorinated) ponytails and tested their activity in ring‐closing metathesis. The substitution mostly resulted in accelerated reaction but the precatalyst stability often decreased.

The Chemical Record, Volume 26, Issue 1, January 10, 2026.Platinum group pincer complexes are highly efficient catalysts. Additionally, their high activity enables challenging transformations with low catalyst loading. Herein, we summarize the most relevant advances of catalysis involving platinum group pincer complexes. The use of pincer complexes based on platinum group metals is undoubtedly one of the most
