ChemInform Abstract: Photoreactions of the Triruthenium Cluster Ru₃(CO)₁₂ and Substituted Analogues.

Abstract

The medium, ligand, and wavelength effects on the quantum yields and flash photolysis kinetics for the photofragmentation and photosubstitution reactions of the trinuclear Cluster Ru3(CO)12 and Ru3(CO)12‐"L" [L: P(OMe)3, PPh3, P(p‐tolyl)3, P(O‐o‐tolyl)3] are comprehensively investigated.

Photofragmentation kinetics of some triruthenium carbonyl clusters

“…This scheme is a synthesis of Schemes I and I1 suggested for [OS,(CO),~] and is expressed here, for consistency, in essentially the same form as the scheme for [Ru,(CO),,] proposed by Ford and co-workers. 2 The species [M,(CO),,]* is the photochemically excited form of [M,(CO),,]. It relaxes to the chemically reactive cluster [M3(CO)12]** that is isomeric with [M,(CO),,] and that can rapidly form adducts with Lewis bases L or L'.…”
