Special Issue Information

Dear Colleagues,

It is my pleasure to invite you to contribute a manuscript to an upcoming Special Issue of Molecules on “Metal-Induced Molecular Activation and Coupling Reactions”. This Special Issues wishes to explore the ever-expanding subject of molecular activation for creating active sites to conduct coupling reactions, in which any of the functional sites of the activated molecule may be further used to form new molecules. To speed up the reaction and reduce the formation of byproducts, chemists have employed metal as media, which is involved in the formation of organometallic intermediates that promote reaction as well as the formation and activity of catalytic species in homogeneous catalysis. The intention of this issue is to capture the state-of-the-art of metal-promoting coupling reactions, either as mechanistic studies or new reactions, in order to enhance development of new molecules as well as chemical applications in providing building blocks for materials science and chemical drugs. Besides the rapid development of nano and biochemical sciences, the importance and performance of the chemistry and its application still lie at the cutting edge when it comes to the development of new techniques—transforming cheaper substrates into fine chemicals, converting chemicals into functional molecules, and linking small molecules into materials. Your contributions would be highly appreciated in promoting understand of this chemistry and its applications in outlining the latest scientific progress in this area. Furthermore, Molecules is a premier journal which offers a perfect venue for the rapid publication of original and review articles on the topics of molecule transformation, new molecule synthesis, and their applications.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All papers will be peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Molecules is an international peer-reviewed open access semimonthly journal published by MDPI.

6-Arylimino-2-(2-(1-phenylethyl)naphthalen-1-yl)-iminopyridylmetal (Fe and Co) Complexes as Highly Active Precatalysts for Ethylene Polymerization: Influence of Metal and/or Substituents on the Active, Thermostable Performance of Their Complexes and Resultant Polyethylenes

Abstract
A series of 6-arylimino-2-(2-(1-phenylethyl)naphthalen-1-yl)iminopyridines and their iron(II) and cobalt(II) complexes (Fe1Fe5, Co1Co5) were synthesized and routinely characterized as were Co3 and Co5 complexes, studied by single crystal X-ray crystallography, which individually displayed a distorted square pyramidal [...] Read more.
A series of 6-arylimino-2-(2-(1-phenylethyl)naphthalen-1-yl)iminopyridines and their iron(II) and cobalt(II) complexes (Fe1Fe5, Co1Co5) were synthesized and routinely characterized as were Co3 and Co5 complexes, studied by single crystal X-ray crystallography, which individually displayed a distorted square pyramidal or trigonal bipyramid around a cobalt center. Upon treatment with either methyluminoxane (MAO) or modified methyluminoxane (MMAO), all complexes displayed high activities regarding ethylene polymerization even at an elevated temperature, enhancing the thermostability of the active species. In general, iron precatalysts showed higher activities than their cobalt analogs; for example, 10.9 × 106 g(PE) mol−1 (Co) h−1 by Co4 and 17.0 × 106 g(PE) mol−1 (Fe) h−1 by Fe4. Bulkier substituents are favored for increasing the molecular weights of the resultant polyethylenes, such as 25.6 kg mol−1 obtained by Co3 and 297 kg mol−1 obtained by Fe3. A narrow polydispersity of polyethylenes was observed by iron precatalysts activated by MMAO, indicating a single-site active species formed. Full article
