Abstract:
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.

Selection Rules: Thermal Activation
Conjugated systems containing an even number of π-electron pairs undergo a conrotatory ring closure. For example, thermal electrocyclization of (2E,4E)-2,4-hexadiene, a conjugated diene containing two π-electron pairs, gives trans-3,4-dimethylcyclobutene.

As shown below, the mechanism proceeds in two steps. First, one of the alkyl groups of the reagent acts as a nucleophile and attacks the acyl carbon of the acid chloride to form a tetrahedral intermediate. This is followed by the reformation of the carbon–oxygen...
