A versatile synthesis of cyclic molybdenum– and tungsten–carbon σ-bonded complexes
Abstract
A simple dehalogenation takes place when dicarbonyl-(3-chloropropyldimethylarsine)-η-cyclopentadienyliodomolybdenum(II) is treated in tetrahydrofuran with sodium amalgam; the cyclic Mo–C compound so formed undergoes an hydride elimination reaction to give a cationic derivative of chelated allyldimethylarsine.
