Angewandte Chemie, EarlyView.Electrocatalytic polarity inversion of azlactones unlocks their coupling with electron‐rich reaction partners. Triarylamine‐mediated oxidation of the azlactone enolate generates an electrophilic radical intermediate that undergoes selective C4 functionalization with diverse SOMOphiles.

Etching MXene using Sulfuric Acid
, 2018 A new group of two dimensional materials, MXenes, are produced by etching the A-group from MAX phase using Hydrofluoric acid. The purpose in our study is to find out the ideal concentration of sulfuric acid for etching MXenes.

Angewandte Chemie, EarlyView.Modular access to underexplored C5‐sulfenyl thiazoles via an intermolecular Pummerer rearrangement is reported. The methodology exhibits a broad functional group tolerance enabling the seamless design of trisubstituted thiazole cores bearing a sulfur handle for further elaboration.

Angewandte Chemie, EarlyView.A metal‐ and oxidant‐free electrochemical multicomponent di‐functionalization strategy that rapidly converts 1,1‐disubstituted alkenes into α‐tertiary primary amines with simultaneous installation of bio‐relevant sulfur or selenium motifs was devised for late‐stage functionalization. ABSTRACT Quaternary carbon centers, especially those bearing nitrogen,

Dibutyl sebacate as PVC ecoplasticizer—economic synthesis and functional properties
Royal Society Open ScienceOne-third of poly(vinyl chloride) (PVC) applications require plasticization to improve flexibility, softness, and processability. Phthalate esters have been widely used but are now restricted due to their toxicity.

Nippon kagaku zassi, 1963 水溶性カルコン硫酸エステル類を得る目的で,レスアセトフェノン-4-硫酸エステルナトリウム塩をメタノール中,アルカリの存在下,芳香族アルデヒド類と縮合させた。すなわちベンズアルデヒド,ベラトルムアルデヒド,p-オキシベンズアルデヒド,バニリン硫酸エステルを用い,相当するカルコン硫酸エステル類を合成した。またこれらカルコン硫酸エステル類をアルカリ性過酸化水素で処理し,フラボノール類の直接硫酸エステル化では合成することの困難であった任意の位置に硫酸エステル基をもつフラボノール硫酸エステル類を得ることができた。なお ...
