Abstract
- The 1:1 reaction of the carbene-stabilized dithiolene zwitterion 1 with BH <subscript>3</subscript> ·SMe <subscript>2</subscript> gave the dithiolene-based hydroborane 2 and the doubly hydrogen-capped CAAC species 3 via hydride-coupled reverse electron transfer processes. The mechanism of this transformation was probed computationally using density functional theory. The subsequent 2:1 reaction of 2 with 1 resulted in 4 and 3 , suggesting that 1 can mediate the B-H bond activation not only for BH <subscript>3</subscript> but also for monohydroboranes. In the presence of BH <subscript>3</subscript> ·SMe <subscript>2</subscript> , 2 was unexpectedly converted to the corresponding diborane(4) complex 5 through a dehydrocoupling reaction at an elevated temperature.<br />Competing Interests: The authors declare no competing financial interest.<br /> (© 2023 The Authors.
