As a sustainable alternative to the harmful traditional oxidation processes, transition-metal catalysts have recently attracted a lot of interest in acceptorless dehydrogenation reactions of alcohols. Here, using well-defined, air-stable palladium(II)\u2013NHC catalysts (A\u2013F), we demonstrate an effective method for the catalytic acceptorless dehydrogenation (CAD) reaction of secondary benzylic alcohols to produce the corresponding ketones and molecular hydrogen (H2). Catalytic acceptorless dehydrogenation (CAD) has been successfully used to convert a variety of alcohols, including electron-rich\/electron-poor aromatic secondary alcohols, heteroaromatic secondary alcohols, and aliphatic cyclic alcohols, into their corresponding value-added ketones while only releasing molecular hydrogen as a byproduct.<\/jats:p>","DOI":"10.3390\/molecules28134992","type":"journal-article","created":{"date-parts":[[2023,6,26]],"date-time":"2023-06-26T05:11:54Z","timestamp":1687756314000},"page":"4992","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Catalytic Acceptorless Dehydrogenation (CAD) of Secondary Benzylic Alcohols into Value-Added Ketones Using Pd(II)\u2013NHC Complexes"],"prefix":"10.3390","volume":"28","author":[{"given":"Abeer Nasser","family":"Al-Romaizan","sequence":"first","affiliation":[{"name":"Department of Chemistry, Faculty of Science, King Abdul-Aziz University, P.O.
