Título: | Reactivity of [Pt(PtBu3)2] with Zinc(I/II) Compounds: Bimetallic Adducts, Zn–Zn Bond Cleavage, and Cooperative Reactivity |
Autor: | Hidalgo, Nereida; Romero-Pérez, Carlos; Maya, Celia CSIC ORCID; Fernández, Israel; Campos, Jesús CSIC ORCID CVN | Fecha de publicación: | 2021 | Editor: | American Chemical Society | Citación: | Organometallics, April 2021 | Resumen: | Metal-only Lewis pairs (MOLPs) based on zinc electrophiles are particularly interesting due to their relevance to Negishi cross-coupling reactions. Zinc-based ligands in bimetallic complexes also render unique reactivity to the transition metals at which they are bound. Here we explore the use of sterically hindered [Pt(PtBu3)2] (1) to access Pt/Zn bimetallic complexes. Compounds [(PtBu3)2Pt→Zn(C6F5)2] (2) and [Pt(ZnCp*)6] (3) (Cp* = pentamethylcyclopentadienyl) were isolated by reactions with Zn(C6F5)2 and [Zn2Cp*2], respectively. We also disclose the cooperative reactivity of 1/ZnX2 pairs (X = Cl, Br, I, OTf) towards water and dihydrogen, which can be understood in terms of bimetallic frustration | Versión del editor: | https://doi.org/10.1021/acs.organomet.1c00088 | URI: | http://hdl.handle.net/10261/239141 | DOI: | 10.1021/acs.organomet.1c00088 |
