摘要

在不需要化学计量量的Cu- acetyides的情况下，作为高效的σ-Lewis酸催化剂，开发了具有空气稳定性和水分稳定性的阳离子同效性Cu(I)噻唑-2- ylidee配合物，在酮的炔化反应中优于咪唑-2- ylidees。这些配合物具有特殊的操作简单性和稳健性，能够形成键C-C键。结构洞察和DFT研究强调了它们增强的反应性和稳定性。噻唑-2-吡啶具有优异的性能和实用性，是一类很有前途的可持续有机合成催化剂。

Cationic and Homoleptic Copper(I)–Thiazol-2-ylidenes: Highly Reactive Thiazole N-Heterocyclic Carbenes σ-Lewis Acid Catalysts

Air- and moisture-stable cationic homoleptic Cu(I) thiazol-2-ylidene complexes are developed as highly efficient σ-Lewis acid catalysts, outperforming imidazol-2-ylidenes in the alkynylation of ketones without requiring stoichiometric Cu-acetylides. These complexes exhibit exceptional operational simplicity and robustness, enabling key C–C bond formation. Structural insights and DFT studies highlight their enhanced reactivity and stability. With their superior performance and practicality, thiazol-2-ylidenes represent a promising class of catalysts for sustainable organic synthesis.
