works in dual view: (original – optimized image) or single view (optimized image).
You will be able to control compression, number of colors, metadata settings and much more, and select image format (JPEG, GIF or PNG) for your output file. The image optimizer is lightweight, fast and simple to use, yet powerful for advanced users. It uses with a side by side (dual view) or single view interface to compare the original with the optimized image in real time and instantly see the resulting file size. Both experimental investigations and density functional theory calculations on the reaction mechanism were performed, supporting EnT-enabled regioconvergent photocatalytic radical–radical coupling reaction pathways.Radical Image Optimization Tool (RIOT for short) is a free image optimizer that will let you to visually adjust compression parameters while keeping minimum filesize. Notably, the excited state Ir(III) photocatalyst enables selective activation of the unwanted imine products through triplet energy transfer, delivering C-4-functionalized azlactones with high regioselectivity. This strategy is extended to the utilization of simple alkanes as the radical precursors, whereby the aryl redox-active esters play a dual role of an oxidant and a hydrogen-atom-transfer agent. Herein, leveraging on the persistent radical effect, we develop photocatalytic energy transfer-enabled regioconvergent alkylation of azlactones with redox-active esters via radical–radical couplings. However, a vast majority of such transformations are two-electron transfer reactions. C-4-selective functionalization of azlactones provides access to α,α-disubstituted unnatural α-amino acids, which has been extensively investigated in the past decades.
