Molybdenum bromides

In a similar manner, Jt-allyl complexes of manganese, iron, and molybdenum carbonyls have been obtained from the corresponding metal carbonyl halides [5], In the case of the reaction of dicarbonyl(r 5-cyclopentadienyl)molybdenum bromide with allyl bromide, the c-allyl derivative is obtained in 75% yield in dichloromethane, but the Jt-allyl complex is the sole product (95%), when the reaction is conducted in a watenbenzene two-phase system. Similar solvent effects are observed in the corresponding reaction of the iron compound. As with the cobalt tetracarbonyl anion, it is... 

Lithium benzenetellurolate or bromomagnesium benzcnetellurolate and cycloheptatrienyl-(dicarbonyl)molybdenum bromide produced the benzenetellurolato-bridged dinuclear molybdenum complex, dicarbonylbis[l-7-r -cycloheptatrienyl -bis[p-benzeneteUurolato] di-molybdenum( II)1.

Brewer (2) used a slight modification of the vibrational frequencies and internuclear distance estimated by Lofgren (3). He assumed an Mo-Br distance of 2.42 A in all the molybdenum bromides. The electron diffraction study of Spiridonov and Romanov (4) established the structure of MoBr (g) to be a regular tetrahedron with an Mo-Br distance of 2.39t0.02 A ( ). This...
