Chemistry – A European Journal, EarlyView.Surface‐bound ferulate phenolate complexes undergo styrene‐like polymerization on alumina, yielding a polymeric carbonaceous layer that progressively transforms into polyaromatic carbon domains with concomitant release of aromatic products, while parallel surface‐assisted decarboxylation produces 4‐vinylguaiacol. ABSTRACT A fundamental understanding of

Well‐Defined Nickel Precatalysts: Form, Function, and Application
Chemistry – A European Journal, EarlyView.This review provides guidance on which nickel precatalysts to choose for a given application or which properties to prioritize in reaction development. A summary of the ease of synthesis, stability, diversity, accessibility, modularity, and general applicability is provided along with a related infographic.

Religionsvidenskabeligt Tidsskrift, 1995 Samson, socalled "judge" and "nazarite", belongs to the same anti-heroic type as the legendary Amirani from Caucasus, masterly analyzd by George Charachidzé as a transformation of Prometheus. The two of them articulate a form of life which denies culture; their necessarily victorious enemies are women and blacksmiths.

Chemistry – A European Journal, EarlyView.A molecular design strategy combines lignin‐derived aromatic units, sugar‐derived furan groups, and flexible glycol segments to create wet‐spinnable polyurethanes. Thermally reversible Diels–Alder crosslinking chemistry enables formation of crosslinked thermosetting fibers, repeated de‐crosslinking/re‐crosslinking cycles, and tunable fiber properties ...

An optimizing microseismic method for rock burst early warning based on mining production process
Deep Underground Science and Engineering, EarlyView.A classification early warning method of rock burst based on hourly microseismic data is proposed, which can be combined with the on‐site production process to provide more timely warning. Abstract Microseismic (MS) events have been reported in nearly every coal mining country, which could well lead to rock burst in underground coal mines.

Layered π Systems Based on Ferrocenophanes
European Journal of Inorganic Chemistry, EarlyView.Syntheses of a variety of ferrocenophanes and extensions of their π systems are reported. These are performed by Knoevenagel reactions and predominantly lead to syn diastereomers. Eight ferrocenophanes were crystallographically characterized. [1.1]Ferrocenophane was prepared by the literature method along with a small amount of [1.1.1.1]ferrocenophane,

European Journal of Organic Chemistry, EarlyView.More than a century after Albrecht's original proposal, an unexpected synthetic relationship between the historically misassigned Michael adduct type and the genuine Diels–Alder product is revealed. Experimental and theoretical studies show that the Michael adduct is not formed directly from the diene and dienophile, but instead arises through ...

European Journal of Organic Chemistry, EarlyView.Catechol‐based annulated aromatics with carbonyl units are ideal ligands for the formation of titanium(IV) containing lithium‐bridged hierarchical helicates. They allow for the first time the use of amide units to obtain the dimeric helicate‐type complexes.
