Deoxytrifluoromethylation/aromatization of cyclohexan(en)ones to access highly substituted trifluoromethyl arenes
Autor: Pankaj Bhattarai, Mohammed K. Abd El-Gaber, Suvajit Koley, Ryan A. Altman
Publikováno v: Nature Communications, Vol 15, Iss 1, Pp 1-9 (2024)
Abstract Trifluoromethyl arenes (Ar–CF3) are amongst the commonly encountered fluorinated substructures in pharmaceutical, agrochemical, and material sciences. However, predominant methods to access Ar–CF3 possess several limitations, including h

Publikováno v: Nature chemistry
Transition metal-catalyzed C–H functionalization and decarboxylative coupling are two of the most notable synthetic strategies developed in the last 30 years. Herein, we connect these two reaction pathways using bases and a simple Pd-based catalyst

Cu(II) Catalyzed Unsymmetrical Di-oxidation of gem-Difluoroalkenes to Generate α,α-Difluorinated-α-Phenoxyketones, an Unstudied Substructure
Autor: Suvajit Koley, Kaylee Cayton, Douglas L. Orsi, Ryan A. Altman, Gisela A. González-Montiel, M. Ramu Yadav, Paul H-Y Cheong
A Cu-based catalyst system convergently couples gem-difluoroalkenes with phenols under aerobic conditions to deliver α,α-difluorinated-α-phenoxy ketones, an unstudied hybrid fluorinated functional group. Composed of α,α-difluorinated ketone and

Selective photodissociation of highly photoactive Bis-2-benzylidenemalononitrile in solution
Autor: Haddad Boumediene, Sumit Kumar Panja, Suvajit Koley
Publikováno v: Journal of Photochemistry and Photobiology A: Chemistry. 375:18-23
Photophysical study of highly photoactive bis-2-benzylidenemalononitrile (BBM) has been investigated in solution using UV–vis, fluorescence and NMR spectroscopic techniques. The seletive photodissociation can be attributed to the presence of highly

Recent Advances in Transition Metal-Catalyzed Functionalization of
Autor: Suvajit, Koley, Ryan A, Altman
Publikováno v: Isr J Chem
gem-Difluorinated alkenes are readily accessible building blocks that can undergo functionalization to provide a broad spectrum of fluorinated and non-fluorinated products. Herein, we review recent (since 2017) transition metal-catalyzed transformati
