Researchers are common within chemical engineering and are often tasked with creating and developing new chemical techniques, frequently combining other advanced and emerging scientific areas. category: copper-catalystIn an article, authors is Lue, Xue, once mentioned the new application about category: copper-catalyst.
Reactions of (Et4N)[Tp*WS3] [Tp*is hydridotris(3,5-di-methyl-pyrazol-1-yl)borate] with CuSCN in MeCN in the presence of melamine afforded the title neutral dimeric cluster [Cu 4W2(C15H22BN6) 2(NCS)2S6(C2H3N) 2] or [Tp*W(2-S)2(3-S)Cu(2-SCN)(CuMeCN)]2, which has two butterfly-shaped [Tp*WS3Cu2] cores bridged across a centre of inversion by two (CuSCN)- anions. The S atoms of the bridging thio-cyanate ligands inter-act with the H atoms of the methyl groups of the Tp*units of a neighbouring dimer to form a C-H…S hydrogen-bonded chain. The N atoms of the thio-cyanate anions inter-act with the H atoms of the methyl groups of the Tp*units of neighbouring chains, affording a two-dimensional hydrogen-bonded network.
But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! Read on for other articles about !, category: copper-catalyst
