Kinetic and Product Study of the S-oxidation vs HAT Chemoselectivity in Reactions Promoted by Nonheme Iron(IV)-oxo Complex/NHPI Mediator System [PDF]

, 2023
The chemoselectivity between S-oxidation and hydrogen atom transfer (HAT) from C−H bonds has been investigated in the oxidations of a series of aryl sulfides, alkyl aromatic compounds and benzylic alcohols promoted by the iron(IV)-oxo complex [(N4Py)FeIV(

Recent Progress on Photoelectrochemical Organic Upgrading: A Review from Direct and Indirect Charge Transfer Pathway

Advanced Energy Materials, Volume 15, Issue 48, December 23, 2025.
Photoelectrochemical (PEC) organic upgrading at the anode, coupled with hydrogen evolution at the cathode, presents a promising strategy for enhancing solar energy utilization while simultaneously generating value‐added chemicals. An overview of directional photoanodic conversion of organic substrates is presented, distinctively with an eye to the ...

Ketene Reactions with the Aminoxyl Radical TEMPO:  Preparative, Kinetic, and Theoretical Studies [PDF]

The Journal of Organic Chemistry, 2001
Tetramethylpiperidinyloxy (TEMPO, TO*) reacts with ketenes RR(1)C=C=O generated by either Wolff rearrangement or by dehydrochlorination of acyl chlorides to give products resulting from addition of one TEMPO radical to the carbonyl carbon and a second to the resulting radical.

A Scalable Synthesis of a New Quasi‐Reversible Redox Compound with a High Positive Redox Potential

ChemElectroChem, Volume 12, Issue 19, October 3, 2025.
A new redox active molecule with an extraordinary high redox potential of +1.45 V vs standard hydrogen electrode (SHE) is found. To elucidate the electrochemical redox mechanism of the 1,4‐diallyl‐2,5‐bis(allyloxy)benzene a series of model compounds was developed and electrochemically characterised.

Organic Spin‐State Photoswitches

Angewandte Chemie International Edition, Volume 64, Issue 38, September 15, 2025.
Spin‐state photoswitching has become a field of broad interest in the last decades due to unique physical and chemical properties accessible from controlling the spin state of a molecular entity. This review gives an overview of the different types of materials and classifies them into photoconformational and photochemical switches depending on the ...

Practical and stereoselective electrocatalytic 1,2-diamination of alkenes [PDF]

, 2019
1,2-二胺结构广泛存在于天然产物、药物和不对称合成中使用的催化剂中。烯烃双胺化，即在烯烃两端同时引入两个氨基，是合成1,2-二胺最为简便和高效的方法之一。但该方法面临着诸多挑战，是有机合成中有待解决的难题。其难点主要是源于二胺产物对过渡金属催化剂的抑制作用以及难以控制反应非对映选择性和区域选择性。徐海超课题组对电化学促进的烯烃双官能团化反应进行了深入研究，通过进一步脱除磺酰基成功实现了高非对映选择性和区域选择性的烯烃双胺化反应，为1,2-二胺类化合物提供高效、简便的合成方法 ...
