Remapping the Synthetic Landscape of α‐Tertiary Alkylamines via Dual‐Functional Catechol
Angewandte Chemie, EarlyView.A three‐component assembly strategy has been developed for the modular synthesis of hindered α‐tertiary aliphatic amines from readily available precursors through unlocking the dual role of catechol. The practicality of this methodology has been demonstrated in over 90 examples, including compounds that are otherwise difficult to access, along with ...

Sustainable Pd‐Catalyzed Aminations “on Dirty Water”
Angewandte Chemie, EarlyView.Aminations, done safely yet neat, and therefore, quickly, using low levels of Pd, in “dirty water” that must contain 30% KOH; not NaOH, and not at 5%,10%, 20%, 40%, or 50% KOH. Moreover, no base sensitivity of functional groups! Very cool. Thank you, Nature.

Rapidly Diversifying Hydrogen‐Bonded Organic Frameworks With Permanent Porosity
Angewandte Chemie, EarlyView.This article reviews diversifying hydrogen‐bonded organic frameworks (HOFs) with permanent porosity reported over the past 15 years, based on the molecular structures of their constituent tectons. Furthermore, several distinctive aspects and concepts are described, such as permanent porosity, isostructural (isoreticular) HOFs, and multicomponent mixed ...

Light induced electropolymerization of aniline [PDF]
, 2005 198-204Electropolymerization of aniline has been carried out in the presence of light. The kinetics of polymer growth has been studied in terms of weight of the aggregate as a function of time in the absence and presence of ZnSO4 and found that zinc ...

The Direct Production of Aniline from Benzene [PDF]
, 1927 Aniline was accurately investigated by A. W. Hoffman in 1843. He was able to show that all of the above products are identical and for them he selected Fritsche's name, aniline.

Selective flow-injection determination of aniline and m-nitroaniline in mixtures containing isomeric nitroanilines and aniline [PDF]
, 1998 Operating conditions for the selective flow-injection determination of aniline and 3-nitroaniline in the presence of isomeric nitroanilines as 5,7-dichloro-4,6-benzofuroxan derivatives of test compounds are determined by varying the flow composition. The

Angewandte Chemie, EarlyView.Eine divergente Aldehyd‐Funktionalisierungssequenz, ermöglicht durch ein anomeres Amid, erlaubt den Ein‐Topf‐Zugang zu unsymmetrischen Harnstoffen, Carbamaten, Thiocarbamaten, Thioestern und Amiden. Entscheidend für diese Transformation ist die Bildung von N‐Boc‐Hydroxamat‐Intermediaten, die als Plattformen für eine orthogonale Aktivierung über Lossen ...
