TL;DR: In this paper, the authors focus on recent progress related to structural modifications made to the pre-catalyst, and in particular to the multidentate N imine -ligand manifold, and how these changes impact on thermal stability and activity of the catalyst as well as the microstructural properties of the polyethylene and the distribution of the oligomeric fractions.

TL;DR: A series of 2,6-dibenzhydryl-N-(2-phenyliminoacenaphthylenylidene)-4-methylbenzenamines (L1−L5) and the nickel(II) dibromide complexes thereof (C1−C5) were synthesized and fully characterized.

TL;DR: A series of iron complexes ligated by 2-imino-1,10-phenanthrolinyl ligands, LFeCl2 (L = 2-(ArNCR)-1, 10-phen), were synthesized and sufficiently characterized by elemental and spectroscopic analysis along with X-ray diffraction analysis.

TL;DR: Diiminopyridyl metal complexes, first characterized several decades ago, found practical application in 1998 when they were used as precatalysts in coordinative ethylene polymerization.
Abstract: Diiminopyridyl metal complexes, first characterized several decades ago, found practical application in 1998 when they were used as precatalysts in coordinative ethylene polymerization. This discovery contributed to the so-called postmetallocene revolution and triggered the large-scale experimental and theoretical research aimed at understanding diversified diiminopyridine chemistry. The results of this quest, some of which were intriguing and difficult to anticipate, are discussed and summarized in the current Review.

TL;DR: In this article, a series of iron(II) (7a−11a) and cobalt(II)-6-(1-(arylimino)ethyl)pyridyl complexes were synthesized and their molecular structures were determined by single-crystal X-ray diffraction analysis.

TL;DR: There is, I think, something ethereal about i —the square root of minus one, which seems an odd beast at that time—an intruder hovering on the edge of reality.
Abstract: There is, I think, something ethereal about i —the square root of minus one. I remember first hearing about it at school. It seemed an odd beast at that time—an intruder hovering on the edge of reality.
Usually familiarity dulls this sense of the bizarre, but in the case of i it was the reverse: over the years the sense of its surreal nature intensified. It seemed that it was impossible to write mathematics that described the real world in …
