gamma-Selective Allylation of (E)-Alkenylzinc Iodides Prepared by Reductive Coupling of Arylacetylenes with Alkyl Iodides

The first examples of Cu-catalyzed gamma-selective allylic alkenylation using organozinc reagents are reported. (E)-Alkenylzinc iodides were prepared by Fe-catalyzed reductive coupling of terminal arylalkynes with alkyl iodides. In the presence of a copper catalyst, these reagents reacted with allylic bromides derived from Morita-Baylis-Hillman alcohols to give 1,4-dienes in high yields. The reactions are highly gamma-selective (generally gamma/alpha > 49:1) and tolerate a wide range of functional groups such as ester, cyano, keto, and nitro

Interaction of He and He-V clusters with self-interstitials and dislocations defects in bcc Fe

The understanding of helium effects in synergy with radiation damage is crucial for the development of structural steels for fusion applications. Recent investigations in ultra-pure iron, taken as a basic model, have shown a drastic impact of dual beam (helium and iron) exposure on the accumulation of radiation-induced dislocation loops in terms of strong bias towards a(0)/2 loops, while a(0) loops are mostly observed upon iron ion beam. In this work we perform a series of atomistic studies to rationalize possible mechanisms through which He could affect the evolution of microstructure and bias the population of a(0)/2 loops. It is shown that He atoms are dragged by gliding a(0)/2 loops. This strongly suppresses loop diffusivity and in turn it prohibits the mutual interaction of a(0)/2 loops, being prerequisite of the formation of a(0) loops, as well as it reduces the disappearance of a(0)/2 loops at sinks. A scenario for the microstructural evolution in the single-and dual-beam conditions is discussed. (C) 2014 Elsevier B. V. All rights reserved.Peer ReviewedPostprint (author's final draft

A Monometallic Iron(I) Organoferrate

Tetra-n-butylammonium (TBA) (eta(6)-biphenyl)diphenyfferrate was formed unexpectedly in the reaction of (TBA)(2)[Fe4S4Cl4] with an excess of phenyllithium. This complex belongs to a novel type of organoferrate

Z-Selective Olefin Synthesis via Iron-Catalyzed Reductive Coupling of Alkyl Halides with Terminal Arylalkynes

Selective catalytic synthesis of Z-olefins has been challenging. Here we describe a method to produce 1,2-disubstituted olefins in high Z selectivity via reductive cross-coupling of alkyl halides with terminal arylalkynes. The method employs inexpensive and nontoxic catalyst (iron(II) bromide) and reductant (zinc). The substrate scope encompasses primary, secondary, and tertiary alkyl halides, and the reaction tolerates a large number of functional groups. The utility of the method is demonstrated in the synthesis of several pharmaceutically relevant molecules. Mechanistic study suggests that the reaction proceeds through an iron-catalyzed anti-selective carbozincation pathway
