ALT The addition of the Si-H bond of silane to a metal fragment often results in an oxidative addition yielding a metal silyl hydride characterized by two covalent bonds M-Si, and M-H. It is speculated that many nonclassical bonding patterns can be observed in the addition of X-H (X=H, B, C, Si) to MLn before reaching the oxidative addition product. (Catal. Lett. 2005, 104, 79-101; J. Phys. Chem. A 2017, 121, 7219-7235). Here using computational techniques, we explore the possible coordination modes of Si-H and other X-H bonds on a PSiP cobalt catalyst developed by Xiaoyan Li (Inorg. Chem. 2021 60 (7), 4551-4562). This will help understand the role of X in these reactions which will be useful in understanding small molecule activation.
