  Secondary bonding. Part 15. Influence of lone pairs on co-ordination: comparison of diphenyl-tin(IV) and -tellurium(IV) carboxylates and dithiocarbamates

  摘要：

  Seven complexes of general type Ph2MX2 with X = carboxylate or dithiocarbamate have been prepared and their molecular structures determined (M = Sn, X = O2CMe, O2CCH2Cl, or S2CNEt2; M = Te, X = O2CCCl3, S2CNEt2, S2CNEtPh, or S2CNPh2). All but one show unsymmetrical bidentate co-ordination by the carboxylate or dithiocarbamate ligands; the tellurium complexes show substantially greater differences between the longer and shorter M-O or M-S distances. The presence of the lone pair transforms the co-ordination geometry from approximately tetrahedral (M = Sn) to pseudo-trigonal bipyramidal (M = Te). Replacing carboxylate by dithiocarbamate has a modest effect when M = Te, but in the tin compound the sulfur ligand co-ordination is almost symmetrical. This contrasts with the unsymmetrical bonding in Me2Sn(S2CNEt2)2.

Identical products were obtained by the metathetical reaction of R2TeCl2 with silver salts of the fluorocarboxylic acids in 1:2 molar ratios. However, when the reaction proceeded in a 1:1 molar ratio, the product

  The present invention relates to the use of telluroxides as mild and selective oxidizing agents serving to oxidize certain functions, notably >C.dbd.S groups, in the presence of other relatively easily oxidized functions which remain unaffected; telluroxides of interest as oxidizing agents include, for example, compounds of the formula: ##STR1## wherein R and R.sup.1, which may be the same or different, each represent an optionally substituted aryl or heterocyclic group; or R and R.sup.1 together with the tellurium atom therebetween represent a heterocyclic ring, which may contain one or more further heteroatoms, and which may carry substituents and/or fused aromatic rings.

  本发明涉及碲氧化物作为温和且选择性的氧化剂的用途，用于氧化特定功能，特别是>C.dbd.S基团，在其他相对容易被氧化的功能存在的情况下保持不受影响；作为氧化剂感兴趣的碲氧化物包括例如下式的化合物：##STR1## 其中R和R.sup.1，可以相同也可以不同，分别代表可选择地取代的芳基或杂环基团；或者R和R.sup.1与其之间的碲原子一起代表一个杂环环，该环可以含有一个或多个进一步的杂原子，并且可以携带取代基和/或融合的芳香环。

  Monothiocarbonate derivatives of diorganotellurium(IV), R₂Te[SCO₂R′]₂, and R₂TeX[SCO₂R′], where R = Me, Ph; R′ = Me, i-Pr; X = Cl, Br, and I, have been prepared and characterized by vibrational and ¹H, ¹³C, and ¹²⁵Te NMR spectroscopy. Me₂Te[SCO₂(i-Pr)]₂ (2): P2₁/n (No. 14) with cell parameters a = 6.942(6) Å, b = 25.599(3) Å, c = 9.404(6) Å, β = 94.48(6)°, V = 1666(1) ų, Z = 4, R = 0.0648, R_w = 0.0624; Ph₂Te[SCO₂(i-Pr)]₂ (4): P2₁/n (No. 14) with a = 12.360(4) Å, b = 12.277(3) Å, c = 15.066(3) Å, β = 102.82(2)°, V = 2229.1(9) ų, Z = 4, R = 0.0368, R_w = 0.0312; Me₂TeCl[SCO₂Me] (5); P2₁/c (No. 14) with a = 5.193(2) Å, b = 18.118(4) Å, c = 9.613(5) Å, β = 91.31(6)°, V = 904.2(6) ų, Z = 4, R = 0.0396, R_w = 0.0361; and Me₂TeBr[SCO₂(i-Pr)] (8): P2₁/n (No. 14) with a = 11.701(2) Å, b = 6.250(2) Å, c = 16.152(2) Å, β = 98.43(1)°, V = 1168.4(4) ų, Z = 4, R = 0.0369, R_w = 0.0325. In all molecules, the immediate environment about tellurium is that of the saw-horse structure in which the lone pair is assumed to be stereochemically active and occupying an equatorial position in a distorted trigonal bipyramid. In 2 and 5, the terminal oxygen atoms are oriented toward tellurium, whereas in 4, one O(i-Pr) group is oriented toward tellurium, as it is in 8. In the latter cases, the terminal oxygen atoms act as weak bridges to form a pseudo dimeric species in 4 and a pseudo polymer in 8. Supramolecular interactions in 2 and 5 lead to a sulfur-bridged dimer in the former and a chlorine-bridged polymer in the latter. Key words: structure, tellurium, dimethyl, diphenyl, monothiocarbonates.
