  摘要：

  We report the use of triorganotin fragments R2L1-2ST, containing N,C,N and O,C,O-Iigands L1-2 (L-1 = C6H3(Me2NCH2)(2)-2,6(-), L-2 = C6H3 ((BuOCH2)-Bu-l)(2)-2,6(-)) on stabilization of both thiol-form in R2L1-2 Sn-2-SPy (2-SPy = pyridine-2-thiolate) and thione-form in R2L1-2 Sn(mimt) (mimt = 1-methylimidazole-2-thiolate) of the polar groups. Treatment of ionic organotin compounds [(Me2LSn)-Sn-1](+)[Cl](-)(1) and [Ph2L2 Sn](+)[OTf](-) (2) with appropriate sodium salts Na-2-SPy and Na(mimt) resulted in the isolation of (Me2LSn)-Sn-1-2-SPy (3), Ph2L2 Sn-2-SPy (4), (Me2LSn)-Sn-1(mimt) (5), (Ph2LSn)-Sn-2(mimt) (6). While polar group 2-SPy exists in its thiol-tautomeric form in compounds 3 and 4, the second polar group (mimt) has been stabilized as the thione-tautomeric form by triorganotin fragments R2L1-2 Sn in compounds 5 and 6. The products were characterized by H-1, C-13 and Sn-119 NMR and IR spectroscopy, ESI/MS, elemental analyses and structures of 3, 6 were determined by X-ray diffraction study. The reactivity of compound 4 containing non-coordinated nitrogen atom of 2-SPy polar group towards CuCl and AgNO3 is also reported. The reactions led to isolation of organotin compounds Ph2L2 SnCl (7) and Ph2L2 SnNO3 (8) as the result of polar group transfer. The mechanism of this reaction has been investigated and compounds Ph3Sn-2-SPy (9) and Ph2L2 Sn-4-SPy (10) (4-SPy = pyridine-4-thic late) have been prepared for this purpose. (c) 2007 Elsevier B.V.

  complex, [Ru2(CO)4(SnPh3)2(μ-pyS)2] (1), the main product of the oxidative-addition of pySSnPh3 to Ru3(CO)12 in refluxing benzene, is [Ru(CO)2(pyS)(SnPh3)] synthon. It reacts with PPh3 to give [Ru(CO)2(SnPh3)(PPh3)(κ2-pyS)] (2) and further with Ru3(CO)12 or [Os3(CO)10(NCMe)2] to afford the butterfly clusters [MRu3(CO)12(SnPh3)(μ3-pyS)] (3, M=Ru; 4, M=Os).
