Preliminary mechanistic investigations reveal a protracted induction period, most likely associated with precatalyst reduction, and these also suggest that the NaOSi<i>^t</i>BuMe-activated B₂pin₂ is not as reducing as the equivalent <i>^t</i>BuLi-activated species. 2026-09-14T00:00:00Z Dataset Dataset 10.1021/acs.organomet.6c00235.s001 https://figshare.com/articles/dataset/Flash_Communication_Siloxides_Promote_the_Iron-Catalyzed_Borylation_of_Aryl_Chlorides/33260582 CC BY-NC 4.0
