Sustainable radical approaches for cross electrophile coupling to synthesize trifluoromethyl- and allyl-substituted tert-alcohols

open access: yesiScience, 2021
Summary: Trifluoromethylated molecules have gained privileged recognition among the medicinal and pharmaceutical chemists. Sustainable photoredox- and electrochemical processes were employed to facilitate the relatively less explored radical cross ...

Homologation of aryl ketones to long-chain ketones and aldehydes via C–C bond cleavage

open access: yesiScience, 2022
Summary: Transition metal-catalyzed C–C bond cleavage is a powerful tool for the reconstruction of a molecular skeleton. We report herein the multi-carbon homologation of aryl ketones to long-chain ketones and aldehydes via ligand-promoted Ar−C(O) bond ...

Neural networks for the prediction organic chemistry reactions [PDF]

open access: yesACS.Cent.Sci. 2 (2016) 725-732, 2016
Reaction prediction remains one of the major challenges for organic chemistry, and is a pre-requisite for efficient synthetic planning. It is desirable to develop algorithms that, like humans, "learn" from being exposed to examples of the application of the rules of organic chemistry. We explore the use of neural networks for predicting reaction types,
