New synthetic route to mono-η5-cyclopentadienylmolylbdenum compounds: X-ray crystal structure of [(η-C5H5)Mo(Ph2PCH2CH2PPh2)(η-C6H8)][PF6]·SO2
Abstract
The compound [(η5-C5H5)Mo(η6-C6H6)Cl]is shown to be a versatile precursor for carbonyl-free monocyclopentadienylmolybdenum derivatives and the new compounds [(η5-C5H5)Mo(dppe)L2][PF6](L2= dppe, (MeCN)2, C4H6, η4-C8H8, Ph2C2, or Me2C2), [(η5-C5H5)Mo(η8-C8H8)][PF6], [η5-C5H5)Mo(η6-C8H8)L][PF6](L = PPh3 or CO), and [(η5-C5H5)Mo(dppe)(C6H8)][PF6] are described (dppe = Ph2PCH2CH2PPh2); the crystal structure of the last compound has been determined.
