Abstract
The synthesis and characterization of a family of carborane-supported macrocycles containing electrophilic mercury centers is described. These compounds are multidentate Lewis acids which have been demonstrated to bind anions such as C1-, Br, I-, and closo-BloHlo2- as well as uncharged nucleophilic species. The lithium salts of the anionic complexes (( 1,2-C2BloH10Hg)&)Li,(l.XnLi,; X = C1, Br, n = 1; X = I, n = 1 or 2) were synthesized from the reaction of closo-1,2-Li~-l,2-C~B~~H~~ with HgX2 (X = C1, Br, and I) in 70-80% yields. The free host ( 12lmercuracarborand-4 (1) was obtained by the removal of halide ions from 1.1~~- with AgOAc. The molecular structures of l-CILi, (l.Br)z- (benzo( 15)crown-5)3-Liz(H20)2, and l*Iz(AsPh4)2 have been determined from single-crystal X-ray diffraction studies. 1.ClLi crystallizes in the tetragonal space group P4/mcc, a = 14.3233(8) A, c = 11.2641(7) A, V = 2311 A3, z = 2 (l/! of the tetramer per asymmetricunit), R = 0.041, R, = 0.060. (l.Br)z(dibenzo( 1 5)crown-5)yLi2(H20)2 crystallizes
