Abstract The η-alkyne complexes [W(CO)(RCCR)3] (R Ph, SMe) react with the ditertiary alkylphosphine Me2PCH2CH2PMe2 (dmpe) in dichloromethane solution at ambient temperature. [W(CO)(MeSCCSMe)3] produces [W(CO)-(dmpe)(MeSCCSMe)2] and eventually [W(dmpe)(MeSCCSMe)2]; with excess dmpe, [W2(dmpe)5(MeSCCSMe)] is formed. All of the alkyne ligands are

Iron overload is a serious clinical condition which can be largely prevented by the use of iron-specific chelating agents. Desferrioxamine-B(1)the most widely used iron chelator in haematology over the past thirty years, has a major disadvantage of being orally inactive’.

Fertilizer Research, 1990
Within the past 20–25 years it has been recognized that many of the micronutrient requirements of plants could be supplied by complexes containing chelated metals. These chelates find uses in a wide variety of agricultural crops such as: corn, bush beans, cucumbers and citrus groves.

Inhibition of Acetylcholinesterase by Chelates I.
Journal of Pharmaceutical Sciences, 1965Inhibition of acetylcholinesterase by 1–1 cupric chelates of ethylenediamine and glycine has been analyzed and shown to be essentially of a noncompetitive type. Inhibition by the 1–1 nickel chelates is weaker than the corresponding cupric chelates; but in contrast to the lack of activity of 2–1 cupric chelates, 2–1 nickel chelates exert significant ...

, 2018 Chelation in Nutrition, Review of Chelation in Plant Nutrition
Journal of Agricultural and Food Chemistry, 1963The use of synthetic chelating agents as a means of supplying Fe and to a lesser extent Zn and Mn to plants is increasing. The manner in which chelating agents function is not as yet fully understood. Chelating agents and their metal components can be absorbed by plant roots and transported to leaves, but there is evidence that chelating agents do not ...

Current Opinion in Hematology, 2014
This review provides an update on advances in the area of iron chelation therapy, including new indications and uses of currently available agents, and preliminary data on potential new agents in development.Two new oral agents, deferasirox and deferiprone, have become available in the last 8 years.
