Pg. Edwards et al., PREPARATION AND SYNTHETIC UTILITY OF MCL(4)(ME(2)NCH(2)CH(2)NME(2))(2), WHERE M IS URANIUM OR THORIUM, Journal of alloys and compounds, 213, 1994, pp. 11-14
UCl4 or ThCl4 dissolves in a solution of Me(2)NCH(2)CH(2)NMe(2) (tmed)
in toluene to give green UCl4(tmed)(2) or colorless ThCl4(tmed)(2). A
nion metathesis with Me(3)SiBr or Me(3)SiI gives UBr4(tmed)(x) or UI4(
tmed)(x), where x lies between 1 and 2. The tmed complexes are useful
synthons for other ligand complexes, as well as for (MeC(5)H(4))(3)ThC
lor (MeC(5)H(4))(4)Th.
