Ruthenium Catalyzed Ortho‐Arylation Reaction of Benzoic Acids with Arylthianthrenium Salts

open access: yesAngewandte Chemie International Edition, EarlyView.
A catalytic ortho‐arylation method has been developed to convert arylthianthrenium salts into carboxylate‐functionalized biaryls, which can be removed in situ or used for further derivatization. This reaction is broadly applicable to (hetero)arenecarboxylic acids, with excellent functional group compatibility and orthogonality to cross‐couplings ...

High-Temperature Oxidation Kinetics of Additively Manufactured NiTiHf [PDF]

open access: yesarXiv, 2020
NiTi-based high-temperature shape memory alloys (HTSMAs) such as NiTiHf have been utilized in a broad range of applications due to their high strength and work output, as well as, their ability to increase the transformation temperatures (TTs). Recently, additive manufacturing techniques (AM) have been widely used to fabricate complex shape memory ...

Reactivity of an iron-oxygen oxidant generated upon oxidative decarboxylation of biomimetic iron(II) α-hydroxy acid complexes.

open access: yesInorganic Chemistry, 2014
Three biomimetic iron(II) α-hydroxy acid complexes, [(Tp(Ph2))Fe(II)(mandelate)(H2O)] (1), [(Tp(Ph2))Fe(II)(benzilate)] (2), and [(Tp(Ph2))Fe(II)(HMP)] (3), together with two iron(II) α-methoxy acid complexes, [(Tp(Ph2))Fe(II)(MPA)] (4) and [(Tp(Ph2))Fe ...

Robust links in photoactive covalent organic frameworks enable effective photocatalytic reactions under harsh conditions

open access: yesNature Communications
Developing heterogeneous photocatalysts for the applications in harsh conditions is of high importance but challenging. Herein, by converting the imine linkages into quinoline groups of triphenylamine incorporated covalent organic frameworks (COFs), two ...

Asparagine Decarboxylation by Lipid Oxidation Products in Model Systems

open access: yesJournal of Agricultural and Food Chemistry, 2010
The decarboxylation of asparagine in the presence of alkanals, alkenals, and alkadienals, among other lipid derivatives, was studied in an attempt to understand the reaction pathways by which some lipid oxidation products are able to convert asparagine into acrylamide.

Direct Integration of Functionalized Bridges by One‐step Superacid‐Catalyzed Reaction to Fabricate Porous Polymers for CO2 Capture and Separation

open access: yesAngewandte Chemie International Edition, Accepted Article.
A novel class of ultra‐microporous functionalized porous organic polymers (POPs) was developed starting from glyoxylic acid as a cross‐linker and triflic acid as a catalyst on polyaromatic monomers, generating in situ methine bridges with carboxylic acids.

Tissue distribution of 5-hydroxymethylcytosine and search for active demethylation intermediates.

open access: yesPLoS ONE, 2010
5-Hydroxymethylcytosine (hmC) was recently detected as the sixth base in mammalian tissue at so far controversial levels. The function of the modified base is currently unknown, but it is certain that the base is generated from 5-methylcytosine (mC ...

Investigation of the catalytic and structural roles of conserved histidines of human coproporphyrinogen oxidase using site-directed mutagenesis [PDF]

open access: yes, 2007
Background: The catalytic contribution of four conserved histidines of human coproporphyrinogen oxidase (CPO) has been investigated using site-directed mutagenesis to change histidine (H) into alanine (A).
