Bidentate N-Heterocyclic carbene complexes of group 13 trihydrides and trihalides.
BAKER, ROBERT (2002)top Treatment of the potentially chelating bis-carbene, 1,2-ethylene-3,3′-di-tert-butyl-diimidazole-2,2′-diylidene, EtIBut, with [MH3(NMe3)], M = Al, Ga, In, in a 1 ∶ 1 or 1 ∶ 2 stoichiometery led to good yields of the ... -
Comments on reactions of oxide derivatives of uranium with hexachloropropene to give UCl4
BAKER, ROBERT (2015)We report that U3O8, UO2(NO3)2·6H2O, and UO2Cl2 react with hexachloropropene (HCP) to give UCl4 in 60, 100, and 92% yields, respectively, and report a protocol to recycle the HCP. This renders the preparation of UCl4 more ... -
Complexes of a gallium heterocycle with transition metal dicyclopentadienyl and cyclopentadienylcarbonyl fragments, and with a dialkylmanganese compound.
BAKER, ROBERT (2006)The reactivity of several transition metal half sandwich complexes towards an anionic gallium(I) heterocyclic complex, [K(tmeda)][Ga{[N(Ar)C(H)]2}] (Ar = C6H3Pri2-2,6), has been investigated. This has led to the anionic ... -
