Stabilization by the electron-accepting boron compounds.
Anionic M0 complexes (M = group 10 metals) have attracted curiosity on account of their potential as lively catalysts for chemical reactions. Despite this, the willpower of their molecular constructions has been a rarity, primarily on account of their extraordinarily excessive reactivity. This holds significantly true for Pt0 complexes, that are anticipated to be extremely reactive. To date, their constructions stay undetermined and the synthesis of those complexes has been practically non-existent.
Associate Professor Hajime Kameo, and Professor Hiroyuki Matsuzaka from the Osaka Metropolitan University Graduate School of Science and CNRS Senior Researcher Didier Bourissou (Paul Sabatier University – Toulouse III) elucidated the molecular constructions of anionic Pt0 complexes for the primary time. The key to success is the stabilization of anionic Pt0 complexes (that are normally unstable owing to their electron-donating nature) by the electron-accepting properties of boron compounds.
“Although platinum complexes that exhibit a variety of catalytic activities have been actively studied, anionic Pt0 complexes have remained a mystery,” said Professor Kameo. “The outcomes of this analysis not solely allow us to elucidate the properties and features of extremely lively chemical species but also provide new guidelines for their creation. It is expected to lead to the development of innovative catalytic reactions mediated by these chemical species.”
