Recent Developments in the Field of Air‐Stable Nickel(0) Precatalysts for Cross‐Coupling Reactions

open access: yesEuropean Journal of Inorganic Chemistry, EarlyView.
The development of bench‐stable Ni(0) sources aims to replace air‐sensitive [Ni(COD)2] (cod = cycloocta‐1,5‐diene) with easy‐to‐handle alternatives. Through a targeted ligand design, using electron‐deficient dienes, carbenes, and fluorophosphines, researchers have achieved air‐ and moisture‐tolerant complexes that show high catalytic activity in cross ...

Creativity and its link to epilepsy

open access: yesEpilepsia Open, EarlyView.
Abstract Creative thinking represents one of our highest‐order cognitive processes, involving multiple cortical structures and an intricate interplay between several cortical and subcortical networks. It results in novel ideas that translate to useful products or concepts. The evolutionary purpose of creativity is therefore apparent, as it advances our

A policy and institutional analysis of urban transport system: the case of Pakistan’s Lahore in the context of COVID-19

open access: yesCogent Social Sciences
The bicycle is recognized as a sustainable mode of transport, yet in the developing world, its use is hindered by several factors. The COVID-19 pandemic, with its emphasis on isolation, created a changed travel pattern and thus an experimental ...

Adolescent Attitudes Towards Active Transportation: Bicycling in Youth in Retrospect from Adulthood [PDF]

open access: yes, 2012
Bicycling as a form of ‘active transportation’ is an easy way to integrate physical activity into a person’s daily life. Bicycling in youth is especially beneficial because it provides physical activity at a time when youth obesity rates are soaring. Yet

Transannular O‐Heterocyclization Reactions of Cyclododeca‐1,5,9‐triene Derivatives: A New Concept for the Preparation of Key Intermediates for Total Syntheses of Annonaceous Acetogenins

open access: yesHelvetica Chimica Acta, EarlyView.
Four stereogenic centers are formed diastereoselectively in one step from a cyclic (E,E)‐1,5‐diene system using an electrophilic addition reaction. Subsequent ozonolytic cleavage of the intact Z‐double bond, followed by intramolecular nucleophilic substitution, yields an octahydroterfurandione with a threo,cis,threo configuration, an arrangement found ...
