The preparation and crystal structure of (η5-C5H5)(OC)3Mo(CH2)3C6H5
摘要:
The reaction of (eta(5)-C5H5)Mo(CO)(3)(-) with p-CH3C6H4S(O)(2)O(CH2)(3)C6H5 produces (eta(5)-C5H5)(OC)(3)Mo(CH2)(3)C6H5. This is only the second structurally characterized organometallic species in which an aromatic moiety is separated by three or more methylene groups. The alkyl chain adopts a staggered conformation, the Mo-C(1)-C(2)-C(3)-C(4) unit is nearly coplanar, and the alkyl chain eclipses the trans-carbonyl group on Mo. NMR evidence indicates that this conformation is preserved in solution. (c) 2006 Elsevier B.V. All rights reserved.
