In 2016,Broman, Soeren Lindbaek; Andersen, Cecilie Lindholm; Jevric, Martyn; Tortzen, Christian Gregers; Hammerich, Ole; Nielsen, Mogens Broendsted published 《Metal cation binding to acetylenic tetrathiafulvalene-pyridine conjugates: affinity tuned by preorganization and cavity size》.Tetrahedron published the findings.Electric Literature of C2H4I2 The information in the text is summarized as follows:
A series of three structurally related mono-, bidentate and macrocyclic TTF-pyridine hosts were prepared and titrated with several metal cations including Ag+ and Pb2+ and studied using NMR- and UV-vis spectroscopy and cyclic voltammetry. For Ag+, we found an eightfold increase in binding affinity between the bidentate and macrocyclic host and conversely, for Pb2+, a 100-fold drop. D. functional theory (DFT) calculations support the increased binding affinity for Ag+ is due to an N···N distance for the uncomplexed macrocycle very much suited for binding of Ag+ but being too small for Pb2+. The bidentate host, on the other hand, is of a suitable size for Pb2+.1,2-Diiodoethane(cas: 624-73-7Electric Literature of C2H4I2) was used in this study.
1,2-Diiodoethane(cas: 624-73-7) is one of organic iodides. Alkyl iodides react at a faster rate than alkyl fluorides due to the weak C-I bond. Iodo alkanes participate in a variety of organic synthesis reactions, which include the SimmonsSmith reaction (cyclopropanation using iodomethane), Williamson ether synthesis, Wittig reaction, Grignard reaction, alkyl coupling reactions, and Wurtz reaction.Electric Literature of C2H4I2
