The facial tricarbonyl complexes (CO)3(L)MnS2CSnPh3 (2a: L = P(OPh)3, 2b: L = P(OMe)3, 2c: L = PPh3, 2d: L = AsPh3, 2e: L = SbPh3, 2f: L = P(c-C6H11)3) are obtained by thermal substitution of the tetracarbonylmanganese complex (CO)4MnS2CSnPh3 (1) with VB donor ligands.With more bulky phosphane ligands, the meridional complexes 3f (L = P(c-C6H11)3) and 3g (L = Ph2PCH2CH2PPh2 (dppe)) are formed by photolytic and thermal substitution, respectively. 3f and g rearrange easily to the more stable facial isomers 2f and 5c.By extended thermal (L = P(OPh)3, P(OMe)3) or by photolytic reactions (L = PPh3, AsPh3, SbPh3) of 1 with the given ligands, the trans-disubstituted products 4a - e are obtained.The rearrangement 4d -> 2d was followed by UV spectroscopy and found to proceed in the stoichiometric ratio 3:2 with k = (1.14 +/- 0.01)*10-4s-1 (t = 25 deg C).Complexes with a monodentate stannanedithiocarboxylate ligand are synthesized by substitution of 1 with bidentate ligand (5c: L = dppe, 5d: L = dipy) or by metathesis of substituted carbonylmetal halides (5b': L = PPh3, M = Re; 5e: 2 L= P(OPh)3, M = Mn).The results show that the thermal substitution is consistent with a dissociative mechanism while the photolytic substitution is assumed to require a ring opening of the chelate ligand.
