Abstract
ABSTRACT Interhalogen and halo-pseudohalogens IX (X=Cl, Br, N3, NCO), (SCN)2, S and TeCl4 add oxidatively to (α-C10H7)3Sb to afford (α-C10H7)3SbIX, (α-C10H7)3 Sb(SCN)2, (α-C10H7)3 SbS and (α-C10H7)3SbCl2, respectively. Reactions of R3SbCl2 (R=α-C10H7, cyclo-C6H11) with MY (M=Ag, K, Na; Y= SCN, CN, NCO, N3) yielded the penta-coordinate products, R3Sb(SCN)2, R3>Sb(NCO)2, (α-C10H7)3Sb(CN)2 and (α-C10 H7)3Sb(N)3)2. The compounds (α-C10H7)3SbIN3, (α-C10H7)3 SbI(NCO), (α-C10H7)3SbI(SCN) and (α-C10H7)3SbI(SeCN) are also accessible by selective replacement reactions of (α-C10H7)3SbICl or (α-C10H7)3SbIBr with the corresponding metal salts. Hydrolysis of R3SbCl2(R=α-C10H7, cyclo-C6>H11) afforded (R3SbCl)2O-type compounds. (α-C10H7)3Sb inserts into the N-chloro bond of N-chlorosuccinimide and N-cholorophthalimide to give and . These haloimides may also be prepared by the interaction of (α-C10H7)3SbCl2 with the corresponding sodium salt of the imido moiety.
