New Twists in the Chemistry of Thioureas: 1,3-Thiazolidines as a Vector of Sustainability, Guillermo Canudo-Barreras, G.; Herrera, R. P.; Gimeno, M. C. Chem. Eur. J. 2024, e202402812, early view. DOI: 10.1002/chem.202402812.

Abstract. This study introduces a sustainable and pioneering cascade synthesis of 1,3-thiazolidine derivatives under eco-friendly conditions. The methodology transcends traditional approaches yielding complex novel compounds with unique N,S-heterocyclic structures. By operating at room temperature, utilizing green solvents, and minimizing excess of reactants, this procedure offers an innovative pathway for sustainable chemical development. Notably, this method not only prioritizes sustainability but also delivers high-purity products with exceptional yields. The simplicity of the process, requiring only a simple filtration and featuring short reaction times, underscores its efficiency and utility.

Exploring Ferrocenyl Imine-Phosphane Complexes in Gold(I) Redox Switchable Catalysis and the Role of the “Magic Blue” Oxidant, Pérez-Sánchez, J. C.; Herrera, R. P.; Gimeno, M. C. Adv. Synth. Catal. 2024, 366, early view. DOI: 10.1002/adsc.202400593. Hot Topic: Gold

Abstract. Another class of gold(I) redox-switchable catalysts, incorporating ferrocenyl phosphane-imines, enriches the existing library of gold(I) complexes. Our catalyst proves efficacy in gold(I)-catalyzed cyclizations of furans and benzamides, exhibiting reversible “on-off” switching. Furthermore, we explored the unconventional role of “Magic Blue”, commonly used as an oxidizing agent in various organic transformations, as a potential activator of the Au−Cl bond, initiating conventional gold(I) catalysis.
