The preparation of ester heterocycles mostly uses heteroatoms as nucleophilic sites, which are achieved by intramolecular substitution or addition reactions. Compound: Mesitylcopper(I)( cas:75732-01-3 ) is researched.Computed Properties of C9H11Cu.Waibel, Markus; Kraus, Florian; Scharfe, Sandra; Wahl, Bernhard; Faessler, Thomas F. published the article 《[(MesCu)2(η3-Si4)]4-: A Mesitylcopper-Stabilized Tetrasilicide Tetraanion》 about this compound( cas:75732-01-3 ) in Angewandte Chemie, International Edition. Keywords: mesityl copper stabilized tetrasilicide tetraanion preparation crystal mol structure; mol structure calculation copper stabilized tetrasilicide tetraanion; Zintl anion. Let’s learn more about this compound (cas:75732-01-3).
The formation of [(MesCu)2Si4]4- (3a) shows that highly charged silicon clusters can be obtained and handled in solution The title anion fills the gap between alkylated Si4R4 cage mols. and the (Si4)4- clusters in binary Zintl phases. The coordination of the MesCu fragment is comparable to the coordination of copper(I) to tetrahedral P4 as it has been reported in [Cu(P4)2]+. The copper atom bridges two P4 mols. which coordinate in η2 fashion. The coordinated P-P bond is also elongated by approx. 0.2 Å compared to the other P-P distances. The [Cu(P4)2]+ ion has been obtained only in the presence of weakly coordinating counter anions. The results show that related ions can be obtained even in the presence of strongly coordinating solvent mols. such as NH3.
