Chemistry can be defined as the study of matter and the changes it undergoes. You¡¯ll sometimes hear it called the central science because it is the connection between physics and all the other sciences, starting with biology. 18742-02-4, Name is 2-(2-Bromoethyl)-1,3-dioxolane, molecular formula is , belongs to copper-catalyst compound. In a document, author is Exner, Rudiger M., SDS of cas: 18742-02-4.
Electrochemical Synthesis of Triphenylphosphine Coinage Metal Complexes stabilized by closo-Dodecaborates [B12X12](2-) (X=H, F, Cl, Br, I)
The synthesis of salts of reactive cations and weakly coordinating anions is of great interest to the development of catalysts, because the weak electrostatic interaction between the two may greatly increase catalytic activity and solubility in nonpolar solvents. However, the synthesis of these salts is in many cases difficult and requires elaborate, sometimes multi-step procedures. Here, we describe the synthesis of a library of monocationic group 11 metal-triphenylphosphine complexes of dodecaborates generated by means of electrochemistry. The complexes of the general formula [M(PPh3)(y)(CH3CN)(z)](2)[B12X12] (M=Cu, Ag, Au; X=H, F, Cl, Br, I; y=2-4; z=0-2) were synthesized from the free acid of the respective dodecaborate and the elemental metal in acetonitrile in the presence of triphenylphosphine. The reactions were performed in an electrochemical cell under ambient conditions in polypropylene containers in all cases. A total of 13 different crystal structures in the [M(PPh3)(y)(CH3CN)(z)](2)[B12X12] system were obtained. As a by-product in some reactions single crystals of [(H3O)(OPPh3)(3)](2)[B12X12] (X=Cl, Br, I) were found.
Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 18742-02-4, in my other articles.
