Reaction of Tricarbonylcyclopentadienyl Molybdenum Anion with 1,3-Dihalopropane

Abstract

Abstract: Reaction of tricarbonylcyclopentadienyl molybdenum anion with X(CH₂)₃X(X=Br,I)in diglyme gave the cyclic carbene of molybdenum complex──CpMoX(CO)₂·CO(CH₂)₂CCH₂.The similar reaction of sila-bridged biscyclopentadienyltricarbonyl molybdenum anion with 1,3-dihalopropane proceeds smoothiy to afford the corresponding sila-bridged bis[cyclic carbene molybdenum]complex,E[C₅H₄MoX(CO)₂·CO(CH₂)₂CH₂]₂(E=Me₂Si,Me₂SiSiMe₂, Me₂SiOSiMe₂).The crystal structure of One(X=I) of the latter complexes was determined by X-ray crystallography.The crystal is triclinic, space group P₁ with α=0.8188(1) nm,b=1.0454(3) nm,c=2.3325(4) nm,α=94.14(2)°,β=94.07(1)°,γ=102.48(2)°,V=1.9306 nm³,Z=2,D_c=1.854 g/cm³。

Key words: Molybdenum anion, Cyclic carbene, Crystal structure
