Abstract

A reaction between 6-methylfulvene and lithium diisopropylamide in THF solution produces vinylcyclopentadienyllithium in yields of 85-95%. The 1H NMR spectrum of this air-sensitive organlithium reagent has been recorded in THF-d8. Reactions of vinylcyclopentadienyllithium with Group VIB metal hexacarbonyls followed by treatment with N-methyl-N-nitroso-p-toluenesulfonamide afford the new vinyl organometallic monomers (η5-C5H4CHCH2)M(CO)2(NO) (M = Mo, W). Vinylcyclopentadienyllithium also serves as a convenient precursor to a series of (η5-vinylcyclopentadienyl)dicarbonylmetal monomers of cobalt, rhodium, and iridium. The 1H NMR spectra of these vinylcyclopentadienylmetal derivatives have been compared as a function of the metal.
