Synthesis using metal atoms of [RuH(η-C₆H₆)(PMe₃)(σ-C₆H₅)], [OsH(η-C₆H₆)(PMe₃)(σ-C₆H₅)], [MnH(η-C₆H₆)(PMe₃)₂], and [Mn(η-C₅H₅)(PMe₃)₃]: arene ligand-exchange reactions of [RuH(η-C₆H₆)(PMe₃)(σ-C₆H₅)]

Abstract

Co-condensation of atoms of ruthenium, osmium, or manganese with benzene–trimethylphosphine gives [RuH(η-C6H6)(PMe3)(σ-C6H5)], [OsH(η-C6H6)(PMe3)(σ-C6H5)], and [MnH(η-C6H6)(PMe3)2], respectively. Manganese atoms react with cyclopentadiene–trimethylphosphine giving [Mn(η-C5H5)(PMe3)3] which is protonated by HBF4 giving [MnH(η-C5H5)(PMe3)3]BF4. Heating [RuH(η-C6H6)(PMe3)(σ-C6H5)] in [2H6] benzene, toluene, o-, m-, or p-xylene, or mesitylene causes ligand-exchange reactions giving [RuD(η-C6D6)(PMe3)(σ-C6D5)], [RuH(η-C6H5Me)(PMe3)(σ-C6H4Me-m or -p)], [RuH(η-C6H4Me2-1,2)(PMe3)(σ-C6H3Me2-3,4)], [RuH(η-C6H4Me2-1,3)(PMe3)(σ-C6H3Me2-3,5)], [RuH(η-C6H4Me2-1,4)(PMe3)(σ-C6H5)], and [RuH(η-C6H3Me3-1,3,5)(PMe3)(σ-C6H5)] respectively.
