RT Journal Article T1 Synthesis and Coordination of a Bisphosphine-[NHC-borane] Compound: A Ligand Framework for Bimetallic Structure Featuring a Boron-Bridging Moiety A1 Camy, Aurèle A1 Vendier, Laure A1 Bijani, Christian A1 Fernández López, Israel A1 Bontemps, Sèbastien AB We report herein the synthesis of a bisphosphine- [NHC-BH3] compound and its coordination toward gold. The ligand is shown to support a bimetallic structure bisphosphine- [NHC-BH3](AuCl)2. The abstraction of one chloride from the gold metal center triggers the activation of a BH3 fragment, leading to the reductive elimination of H2 and the formation of a dicationic Au4 2+ complex featuring Au centers at the +0.5 oxidation state, via a (μ-H)Au2 intermediate, characterized in situ at 183 K. The reactivity of Au4 with thiophenol led to the reoxidation of the gold metal centers to a (μ-S(Ph))Au2 complex. In the different complexes, borane fragment was shown to bridge the Au2 core via weak interaction with [BH], [BCl], and [BH2] moieties PB ACS SN 0020-1669 YR 2023 FD 2023 LK https://hdl.handle.net/20.500.14352/93582 UL https://hdl.handle.net/20.500.14352/93582 LA eng NO Aurèle Camy, Laure Vendier, Christian Bijani, Israel Fernández, and Sébastien Bontemps Inorganic Chemistry 2023 62 (23), 9035-9043DOI: 10.1021/acs.inorgchem.3c00785 NO Ministerio de Ciencia, Innovación y Universidades (España) DS Docta Complutense RD 8 abr 2025
