Synthesis of binuclear and trinuclear cluster halides of molybdenum and rhenium, and of carbonyl halides of rhenium, iridium, ruthenium, and platinum using metal atoms
Abstract
Reactive halocarbons such as 1,2-dibromo-(or dichloro-) ethane or allyl chloride will halogenate atoms of molybdenum and rhenium under co-condensation conditions giving solvated transition metal halides in lower valency states, e.g.[Re3Cl9(THF)3](THF = tetrahydrofuran), which are useful synthetic precursors; co-condensation of rhenium with oxalyl chloride gives [Re(CO)4Cl]2, ruthenium atoms when co-condensed with oxalyl chloride give a carbonyl halide compound which adds trimethylphosphine forming [Ru(Me3)P3(CO)Cl2], and similarly, iridium atoms with oxalyl chloride and then triphenylphosphine give [Ir(CO)2(PPh3)Cl3].
