Unexpected Reactivity of a PONNOP ‘Expanded Pincer’ Ligand

25 March 2020, Version 1
Working Paper
This content is a preprint and has not undergone peer review at the time of posting.

Abstract

We report the synthesis, characterization and coordination chemistry of a new naphthyridine-derived phosphinite PONNOP expanded pincer ligand. As envisioned, the dinucleating ligand readily binds two copper(I) centers in close proximity, but undergoes an unexpected rearrangement in the presence of nickel(II) salts to form an interesting PONNP pincer platform.
