Staged Diversity‐Constrained Machine Learning for High‐Dimensional Reaction Condition Optimization

Angewandte Chemie, EarlyView.
Staged diversity‐constrained modeling enables efficient navigation of high‐dimensional reaction spaces, validated on cross‐coupling HTE data and applied to ruthenium‐catalyzed meta‐C─H functionalization. ABSTRACT Optimizing reaction conditions in high‐dimensional chemical spaces remains a central challenge in modern synthesis.

A Convenient, Safe, and Atom‐Economical Route to a Large Portfolio of Grubbs‐Type Catalysts for Olefin Metathesis via Four‐Coordinate Ruthenium Alkylidynes

Angewandte Chemie, EarlyView.
It may seem counterintuitive to first target a ruthenium alkylidyne when Grubbs‐type ruthenium carbene complexes are the actual goal. In the end, however, this tactic pays valuable dividends in terms of practicality, atom economy, flexibility as well as safety: the new route provides ready access to a large assortment of catalysts for alkene metathesis

Out‐of‐Equilibrium Supramolecular Assembly Sustained by Photocatalysis

Angewandte Chemie, EarlyView.
Catalysis sustains structure: A Pt(II) supramolecular photocatalyst persists in a far‐from‐equilibrium state only as long as it remains photocatalytically active. Without ongoing catalytic activity, the system irreversibly relaxes into a thermodynamically stable but inactive state (PtB). Catalysis is essential for sustaining its structure.
