So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic.Niemeyer, Mark researched the compound: Mesitylcopper(I)( cas:75732-01-3 ).Safety of Mesitylcopper(I).They published the article 《Reaction of copper aryls with imidazol-2-ylidenes or triphenylphosphine. Formation of 1:1-adducts with two-coordinate copper atoms》 about this compound( cas:75732-01-3 ) in Zeitschrift fuer Anorganische und Allgemeine Chemie. Keywords: imidazolylidene reaction copper aryl; triphenylphosphine reaction copper aryl; copper aryl carbene complex preparation structure DFT; crystal structure copper two coordinate aryl imidazolylidene triphenylphosphine adduct; mol structure copper two coordinate aryl imidazolylidene triphenylphosphine adduct. We’ll tell you more about this compound (cas:75732-01-3).
The reaction of the Cu aryls CuDmp (Dmp = 2,6-Mes2C6H3; Mes = 2,4,6-Me3C6H2) and CuMes with the σ-donors PPh3 and 1,3-diisopropyl-4,5-dimethylimidazol-2-ylidene [C[N(i-Pr)CMe]2] affords the adducts DmpCu←PPh3 (1), DmpCu←C{N(i-Pr)CMe}2 (2) and MesCu←C{N(i-Pr)CMe}2 (3) in 65-84% yields. The colorless compounds were characterized by 1H and 13C NMR spectroscopy, single crystal structure anal., and also by 31P NMR spectroscopy of 1, elemental anal. of 2, mass spectrometry of 2 and 3, IR spectroscopy of 2 and m.p. of 2 and 3. In the solid-state structures the two-coordinate Cu atoms have relatively short Cu-P and Cu-C(carbene) distances of 218.91(11) of 1, 190.2(3) of 2 and 191.1(4) pm of 3. DFT calculations at the B3PW91 level were performed for the model compound PhCu←C[N(H)CH]2 and also for the free carbene ligand C[N(H)CH]2.
There is still a lot of research devoted to this compound(SMILES：[Cu]C1=C(C)C=C(C)C=C1C)Safety of Mesitylcopper(I), and with the development of science, more effects of this compound(75732-01-3) can be discovered.
