Generative and Experimental Validation of High Refractive Index Polymers via Domain Knowledge Approach with Small Data

open access: yesAdvanced Intelligent Discovery, EarlyView.
This research demonstrates that the combination of domain knowledge–based multiple regression, multi‐objective Bayesian optimization, and generative models is a suitable prediction tool for candidates of high refractive index polymers, even with the constraints in the model trained on limited data. The experimental validation can reproduce the proposed

Die Aza‐Büchner–Curtius–Schlotterbeck‐Reaktion: Selektive Bildung Quartärer Kohlenstoffzentren

open access: yesAngewandte Chemie, EarlyView.
Wir stellen die Aza‐Büchner–Curtius–Schlotterbeck‐(ABCS)‐Reaktion vor: eine milde, katalysatorfreie Methode zur Homologierung von Aryliminen. Im Gegensatz zum traditionellen BCS‐Mechanismus durchläuft das Diazo‐Intermediat eine selektive C─C‐Insertion zur Bildung eines quartären Zentrums.
