An Unusual Conversion of Paramagnetic [3-Cl-3,3,8-{Ph2P(CH2)nPPh-µ-(C6H4-ortho)}-1,2-(CH3)2-closo-3,1,2-RuIIIC2B9H8] (n = 3 and 4) to Form the First 18-Electron P-Phenylene ortho-Cycloboronated closo-Ruthenacarboranes with a Dioxygen Ligand

Abstract

Treatment of 3, P(CH 2 ) n PPh-µ-(C 6 H 4 -ortho)]-1,2-Me 2 -closo-3,1,2-Ru III C 2 B 9 H 8 ] (1, n = 3; 2, n = 4) with an excess of KOH in a 1:1 benzene/methanol mixture at room temperature in air affords new dioxygen closo-ruthenacarborane complexes [3-(η

Special Issue on Ruthenium Complexes

“…The submitted contributions can be roughly grouped into four categories: (1) synthesis of new ruthenium complexes, (2) applications in organic synthesis and catalysis, (3) photocatalysis and dye-sensitized solar cells, and (4) medicinal chemistry. With the exception of the article of Igor T. Chizhevsky et al [ 4 ], which deals with the synthesis and characterization of new closo -ruthena-carborane complexes with a dioxygen ligand, most of the contributions actually fall into two or even three categories, so that the following summary of the special issue is by no means a strict classification.…”
