Alkyl, olefin, and carbonyl derivatives of bis(η-cyclopentadienyl)-molybdenum and -tungsten
Abstract
The compounds [Mo(η-C5H5)2R(CO)][PF6](R = Me, σ-C3H5, CH2OMe, COMe, CH2CO2Me, or CH2CN) and [W(η-C5H5)2Me(CO)][PF6], have been prepared by addition of RX to [Mo(or W)(η-C5H5)2(CO)]. Similarly, the compounds [W(η-C5H5)2(C2H4)R″][PF6](R″=σ-C3H5, CH2CN, and CH2CO2Me) have been prepared by addition of R″X to [W(η-C5H5)2(C2H4)]. Treatment of [Mo(η-C5H5)2Me(CO)][PF6] with PMe2Ph gives [Mo(η-C5H5)2(COMe)(PMe2Ph)][PF6]. The compounds [W(η-C5H5)2(CH2CN)Cl]. [W(η-C5H5)2(CH2CN)(PMe2Ph)][PF6], [W(η-C5H5)2(η-MeC2Me)Me][PF6], [W(η-C5H5)2(O2CC6H4Br-o)Me], and [W(η-C5H5)2(O2CC6H4OH-o)Me] are also described.
