Tetrakis-/i-(carboxylato)-dimolybdenum(II) complexes have been obtained by only one general route, namely by the direct interaction of carboxylic acids with molybdenum hexacarbonyl.8 This reaction requires elevated reaction temperatures and prolonged reaction times. These same compounds are obtained in comparable or better yields by the brief reaction of tetrachloro- or tetrabromotetrakis(tributylphosphine)dimolybdenum(II) with alkyl- or aryl-carboxylic acids in refluxing benzene. The bis-/i-(arylcarboxylato) complexes... 

Tetrahydrofuran (THF) (80 mL, freshly distilled from sodium benzophenone ketyl) is added from a 250-mL Schienk flask to bis(acetonitrile)tetrachloro-molybdenum(IV) (20 g, 0.052 mole) in a 250-mL Schienk flask and the mixture is stirred rapidly for 2 hours to give a yellow suspension of tetrachlorobis-(tetrahydrofuran)molybdenum(IV). The complex is filtered through a Schienk filter, washed with THF (20 mL), and dried in vacuo (10 2 torr) at room temperature. The product is obtained as a microcrystalline orange-yellow powder in yields of 15-17 g, 63-71%. The product is not analytically pure. Anal. Calcd. for CbH1602C14Mo C, 25.1 H, 4.9. Found C, 26.5 H, 4.2. However, it is sufficiently pure for subsequent reactions.
