The syntheses and spectroscopic (NMR, MS) investigations of the antimonates [Ph4P]+[Me2SbCl4]− (1), [Me4Sb]+[Me2SbCl4]− (2), [Et4N]+[Ph2SbCl4]− (3), [Bu4N]+[Ph2SbCl4]− (4), [Me4Sb]+[Ph2SbCl4]− (5), [Et3MeSb]+[Ph2SbCl4]− (6), [Et4N]+[Ph2SbF4]− (7) and [Et4N]+[Ph2SbBr4]− (8) are reported. Halogen scrambling reactions of Et4NBr or Ph4EBr (E = P, Sb) with R2SbCl3 (R = Me, Ph) produce mixtures of compounds
锑酸盐[Ph 4 P] + [Me 2 SbCl 4 ] -(1),[Me 4 Sb] + [Me 2 SbCl 4 ] -(2),[Et 4 N] + [Ph 2 SbCl 4 ] -(3),[Bu 4 N] + [Ph 2 SbCl 4 ] -(4),[Me 4 Sb] +[Ph 2 SbCl 4 ] -(5),[Et 3 MeSb] + [Ph 2 SbCl 4 ] -(6),[Et 4 N] + [Ph 2 SbF 4 ] -(7)和[Et 4 N] + [Ph 2 SbBr 4 ] -(8)被报道。Et 4 NBr或Ph 4 EBr(E = P,Sb)与R 2 SbCl 3的卤素加扰反应(R = Me,Ph)生成化合物的混合物,其中[Et 4 N] + [Ph 2 SbBr 1.24 Cl 2.76 ] -(9),[Et 4 N] + [Ph 2 SbBr 2.92 Cl 1.08
