Transition-metal-catalyzed C-C coupling reactions have been extensively studied in the past three decades. These reactions have become invaluable to fundamental research and industrial applications, because they can be used construct complicated molecules ...
A copper-based method is highly efficient for the cross-coupling of alkyl electrophiles with secondary and tertiary alkyl Grignard reagents. The method is distinguished by its broad substrate scope and high functional group tolerance. ...
A nickel pincer complex is found to catalyze alkyl–alkyl Kumada coupling reactions of 1,3- and 1,4-substituted cyclohexyl halides and tetrahydropyrans with an excellent diastereoselectivity. The mechanistic investigation of the coupling reactions provides ...
A nickel pincer complex, Nickamine, is shown to be an active catalyst for a large number of reactions including cross coupling of non-activated alkyl halides and direct C-H alkylation of alkynes and aromatic heterocycles. This work was rewarded by the 2011 ...
Imidazolium salts with aromatic groups 1,3-bis(9-anthracenylmethyl)imidazolium chloride ([Bamim]Cl), 1,3-bis(1-naphthalenylmethyl)imidazolium chloride ([Bnmim]Cl) and 1,3-bis( benzylmethyl)imidazolium chloride ([Bbmim]Cl) were reacted with PdCl2 forming th ...
We present an extension of cross-recurrence analysis for dual gaze analysis which is suited for complex situations where for instance the objects of interest are not all visible at all times or when stimulus exploration is not homogeneous. The typicical si ...
Two new bis(diphenylphosphino) amines, N,N-bis(diphenylphosphino) benzidine 1 and N, N-bis(diphenylphosphino)- 3,3-dimethoxybenzidine 2 were prepared by aminolysis. Their corresponding oxides, sulfides and selenides were readily prepared by reaction with h ...
Cross coupling of non-activated alkyl halides is a potentially transformative methodology in organic synthesis. Herein we review the recent development of nickel-catalyzed coupling of non-activated alkyl halides. The current understanding of the mechanism ...
We study systems of identical coupled oscillators introducing a distribution of delay times in the coupling. For arbitrary network topologies, we show that the frequency and stability of the fully synchronized states depend only on the mean of the delay di ...
Dark matter, gauge coupling unification, and the strong CP problem find a common and simple solution (in the absence of naturalness) within axion models. We show that such a solution, even without specifying the details of the model implementation, makes t ...
