The process does not require an inert atmosphere and tolerates the presence of air and water. This non-noble catalytic system shows high chemoselectivity, allowing a diverse range of potentially reducible functional groups such as alkynes, alkenes, halogens, cyano, and carbonyls. Moreover, this strategy enables the reuse of a waste byproduct as reactant, facilitating the formation of challenging 1,4-dicarbonyls from accessible cyclobutane-1,2-diols used as reducing agents. 2025-05-28T07:16:54Z 2025-05-28T07:16:54Z 2024-10 info:eu-repo/semantics/article 1615-4150 http://hdl.handle.net/10259/10505 10.1002/adsc.202401170 1615-4169 eng Advanced Synthesis & Catalysis. 2024, V. 367, n. 4, p. e202401170 https://doi.org/10.1002/adsc.202401170 http://creativecommons.org/licenses/by-nc/4.0/ info:eu-repo/semantics/openAccess Atribución-NoComercial 4.0 Internacional Wiley
