Synthesis, Structures, and Some Reactions of [(Thioacyl)thio]- and (Acylseleno)antimony and -bismuth Derivatives ((RCSS)xMR and (RCOSe)xMR with M = Sb, Bi andx = 1–3)
Despite the large atomic radii, the CS ⋅⋅⋅ Sb distances in (RCSS)2MR1 (M = As, Sb, Bi; R1 = aryl) and the CO ⋅⋅⋅ Sb distances in (RCOS)xMR (M = As, Sb, Bi; x = 2, 3) are comparable to or shorter than those of the corresponding arsenicderivatives (Tables 2 and 3). A molecular-orbital calculation performed on the model compounds (MeC(E)E1)3−xMMex (M = As, Sb, Bi; E = O, S; E1 = S, Se; x = 1, 2) at the

p-TolSbH2 reacts with styrene with formation of ethylbenzene and (p-TolSb)n (n=4, 5 in benzene). The action of phenyl acetylene on p-TolSbH2 gives styrene. Addition of Ph2SbH on phenyl acetylene in the presence of AIBN (azodiisobutyronitrile) yields 95% trans- and 5% cis-PhCHCHSbPh2. Ph2SbH reacts with benzaldehyde in the presence of AIBN with formation of benzylalcohol (98%) and with various prochiral

[2-(Ar′S)C6H4]nBiAr3–n have been conveniently synthesized by insertion of benzyne into the bismuth–sulfur bond of (Ar′S)nBiAr3–n (n = 1, 2). A similar insertion takes place when a homologous antimony congener is used, but no reaction is observed with its phosphorus analogue. This suggests a clear difference in the bond strength between pnictogen–sulfur bonds. The carbon–bismuth bond of [2-(2-BrC6H4S)C6H4]nBiAr3–n

We have synthesized and structurally characterized three tetra-(p-tolyl)antimony(III)-containing heteropolytungstates, [(p-tolyl)SbIII}4(A-α-XW9O34)2]n- [X = PV (1-P), AsV (1-As), or GeIV (1-Ge)], in aqueous solution using conventional, one-pot procedures. The polyanions 1-P, 1-As, and 1-Ge were fully characterized in the solid state and in solution and were shown to be soluble and stable in aqueous
Dithienostiboles having a stibole ring fused with a bithiophene system were prepared by the reactions of β,β′-dilithiobithiophene derivatives with aryldichlorostibines. Their optical properties were examined with respect to the UV absorption and emission spectra. DFT calculations on a model were also carried out to understand the electronic states.
