Abstract

The U4+ metallocene allyl chloride complexes (C5Me5) 2U [η3-CH2C (R) CH2] Cl (R= H, Me) can be synthesized by reaction of (C5Me5) 2UCl2 with 1 equiv of the corresponding allyl Grignard reagents,[CH2C (R) CH2] MgCl, in hydrocarbon solvents. Bis (allyl) uranium complexes can also be obtained in this manner using 2 equiv of the corresponding allyl Grignard, and X-ray crystallographic studies reveal the presence of both η3-and η1-allyl ...
