摘要: Abstract Reaction of NaRu(CO)2C5H5 with excess allyl chloride gives the yellow liquid σ-allyl derivative (σ-C3H5)Ru(CO)2C5H5. Ultraviolet irradiation this in hexane solution results decarbonylation to give pale crystalline π-allyl (π-C3H5)RuCOC5H5. The proton n.m.r. and infrared spectra solutions at 29° both indicate presence two stereoisomers a ∼4:1 ratio. mass various derivatives cyclopentadienylmetal carbonyls molybdenum, ruthenium, tungsten, are compared. undergo spectrometer ∼210° corresponding derivatives.
