Correction to “Metal-Free Amino(hetero)arylation and Aminosulfonylation of Alkenes Enabled by Photoinduced Energy Transfer”

Abstract

In Scheme 3, as well as in the Supporting Information, the structures of compounds 75−79 were drawn incorrectly. The structures of these five products obtained are actually derived from oxyimination reaction of alkenes without decarboxylation. 1 The corrected structures of 75−79 are shown below in the updated Scheme 3, and a revised Supporting Information file is provided with the updated data for compounds 76a−79a and 77b. Scheme 3. Substrate Scope of (Hetero)aryl Radical Precursor a,b a Reaction conditions: a (0.20 mmol, 1.0 equiv), b (0.40 mmol, 2.0 equiv), 2-iPr-thioxanthone (0.01 mmol, 5 mol %), 10 W 390 nm LEDs, under N 2 atmosphere, r.t. in ethyl acetate (3.0 mL, 0.07 M) for

Visible Light‐Enabled Decarboxylative Alkylation of Quinoxalin‐2(1H)‐ones using Alkyl Carboxylic Acids via Energy Transfer Process

“…In the past decade, visible light catalysis has witnessed a remarkable accomplishment through the introduction of energy transfer processes (EnT) and electron transformations. [63][64][65][66][67][68][69][70] Speaking of energy transfer processes in the context of the present work, the excited photosensitizers are known to transfer its energy to ground-state molecular oxygen ( 3 O 2 ) to generate singlet oxygen ( 1 O 2 ), to attain selective chemical transformations. [71][72][73] Also, literature precedents suggested that quinoxalin-2(1H)-ones could assist energy transfer to ground-state molecular oxygen ( 3 O 2 ) to generate a singlet oxygen ( 1 O 2 ), to accomplish the chemical conversions.…”
