Reactivity of [Pt(P ^t Bu₃)₂] with Zinc(I/II) Compounds: Bimetallic Adducts, Zn-Zn Bond Cleavage, and Cooperative Reactivity.

ABSTRACT: 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(P ^t Bu₃)₂] (1) to access Pt/Zn bimetallic complexes. Compounds [(P ^t Bu₃)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/
