The multi\u2010borylated arenes, on the other hand, have received much less attention because the preparation of multi\u2010borylated arenes in a straightforward manner is still underdeveloped. Herein, we present our findings on synthesizing bis\u2010borylated arenes from structure\u2010diverse and readily available aryl halides (Ar\u2500X, X\u00a0=\u00a0Cl, Br, I). Simultaneous C\u2500X and C\u2500H borylation of aryl halides is achieved using earth\u2010abundant titanium as a catalyst. Not only the 1,2\u2010bis borylation but also the 1,3\u2010 and 1,4\u2010bis borylation are achieved. Control experiments and density functional theory (DFT) computations propose a titanium\u2010mediated aryl radical\u2010driven reaction resulting in selective bis\u2010borylation over mono\u2010borylation.<\/jats:p>","DOI":"10.1002\/anie.202509778","type":"journal-article","created":{"date-parts":[[2025,5,26]],"date-time":"2025-05-26T11:10:19Z","timestamp":1748257819000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Titanium\u2010Catalyzed C\u2500X and C\u2500H Borylation of Aryl Halides for the Synthesis of Bis(boronate)benzenes"],"prefix":"10.1002","volume":"64","author":[{"given":"Xiaoxian","family":"Li","sequence":"first","affiliation":[{"name":"State Key Laboratory of Low Carbon Catalysis and Carbon Dioxide Utilization Lanzhou Institute of Chemical Physics (LICP) Chinese Academy of Sciences  Lanzhou 730000 P.R.
