N‐Alkoxysulfurdiimide Reagents for the One‐Step Modular Synthesis of Primary Sulfonimidamides
Angewandte Chemie, EarlyView.N‐Alkoxysulfurdiimide reagents when combined with organometallic reagents lead directly to primary sulfonimidamide products. The reactions are broad in scope, encompassing aryl, heteroaryl, and alkyl carbon substituents. The reactivity of the N‐alkoxysulfurdiimide reagents can be correlated with the electron‐withdrawing ability of the N‐substituent ...

From Berzelius to Hyperspace: Previously Unrecognized Network of Reactivity in Textbook Brominations
Angewandte Chemie, EarlyView.Robotic scans across multidimensional condition spaces of classic bromination reactions uncover regions of previously unrecognized reactivity, yielding new major products and novel substitution patterns. Correlation and anticorrelation analyses of product distributions across these hyperspaces enable reconstruction of the underlying mechanistic ...

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.

Crystal structure of diethyl (E)-2-[(benzofuran-2-yl)methylidene]succinate
Acta Crystallographica Section E: Crystallographic Communications, 2015 The title compound, C17H18O5, was synthesized by a base-free catalytic Wittig reaction. The molecule consists of a diethyl itaconate unit, which is connected via the C=C double bond to a benzofuran moiety. The benzofuran ring system (r.m.s. deviation = 0.

Benzofuran Derivatives. I. On the Effects of Substituents in Benzofuran Syntheses [PDF]
Bulletin of the Chemical Society of Japan, 1983 Abstract The Rössing’s reaction of 4-substituted 2-acylphenoxyacetic acids give a mixture of benzofurans and 2-benzofurancarboxylic acids. The relative yields of benzofurans and 2-benzofurancarboxylic acids depend on the substituents on the benzene ring of the 2-acylphenoxyacetic acids.
