Disproportionation of organo-ditin and -dilead compounds (R3M)2 (M = Sn, Pb) with organic dichalcogenides (R'Z)2 (Z = S, Se, Te) is efficiently promoted by room light to produce the corresponding organo-tin and -lead chalc

The reactivity of di- and triphenyltin(IV) hydroxamate complexes of composition (C6H5)2SnCl2-n(XBHA)n and (C6H5)3Sn(XBHA) (n = 1 and 2; X = p-OMe, o-Cl, p-NO2; BHA = anion of XArCONHOK) with ligands containing labile protons such as acetylacetone (acacH), dibenzoylmethane (dbmH), salicylaldehyde (salH) and o-chlorophenol and thiophenol has been studied to investigate the preferential attack on Sn-C, Sn-Cl or Sn-O bond. The title complexes do not react with the chelating ligands. However, the reactions of (C6H5)2SnCl(XBHA) with sodium salt of the chelating ligands NaL (L= acac, dbm and sal) readily proceed to yield the mixed ligand complexes of composition (C6H5)2Sn(XBHA)*L, while the treatment of (C6H5)2Sn(XBHA)2 and (C6H5)3Sn(XBHA) with phenols results in the complete displacement of the hydroxamate group with the phenolate ion.

Multinuclear nmr (1H, 77Se, 111/113Cd, 119Sn, 199Hg, as appropriate) has been used to study Y(1-) - EPh(1-) exchange in Me2CO or MeCN between (RnM'Y (RnM' = Ph3Sn or MeHg; Y = Cl, Br, I, NCO, or NCS) and the adamantane-like anions (2-) (E = S, M = Zn, Cd, or Co; E = Se, M = Zn or Cd), as their tetraalkylammonium salts.Quantitative terminal substitution of the clusters occurs in most cases, giving 4-x(MY)x>(2-) (x = 1-4).However, reaction is incomplete for M = Cd, E = S or Se, RnM'Y = Ph3SnNCO or Ph3SnNCS and for M = Zn or Co, E = S, RnM'Y = MeHgI.Differences in the extents of reaction for Ph3SnY and MeHgY are consistent with the position of equilibrium in MeHgY:Ph3SnEPh mixtures.Group interchange provides a convenient alternative synthesis of the known halogen-substituted clusters (2-) (M = Zn or Cd, Y = Cl, Br, or I; M = Co, Y = Cl), and the first syntheses of (2-) (Y = Br or I) and various pseudohalogen-substituted adamantanoid anions.The nuclei used for full direct nmr characterization of the new clusters in solution were: 77Se and 113Cd for 4-x(CdY)x>(2-) (x = 1-4; Y = NCO or NCS); 77Se for 4-x(ZnY)x>(2-) (x = 1-4, Y = NCO or NCS); 113Cd for 4-x(CdY)x>(2-) (x = 1-4; Y = NCO or NCS); 1H for (2-) (Y = Br, I, NCO, or NCS).The first solution 1H nmr spectrum of (2-) is also reported.
Thioether complexes of tungsten hexacarbonyl
Lucas, C. Robert
, p. 1758 - 1763 (2007/10/02)
The preparation of a series of organic and organometallic thioethers R3MSR' (M = C,Si,Ge, or Sn) is reported.From these, several new compounds of type 1 are synthesized, some of which contain para-substituted aryl functions for R and R'.In hexane solution in the carbonyl streching region of the ir the uv there is evidence for a degree of multiple bonding, at least in the M - S - WW - CO portion of these molecules.Multiple bonding extending into aromatic R or R'is small or non-existent and cannot be assessed precisely because of spontaneous decomposition of the complexes.All the complexes undergo a thermally initiated decomposition, the case of which depends on the nature of R, R', and M.The unusual W(I) thiolate cis-2 is the termal decomposition product.

3-(Trialkylstannyl)propyl aryl sulphides (R3SnCH2CH2CH2SR′; R = Me, Et, Bu; R′ = Ph, p-tolyl) were prepared by the addition of arenethiols to allyltrialkyltin compounds. Preferential cleavage of the allyl group
