Tri(2-thiophenyl)phosphine (P(C6H4-2-SH)3, PS3) was designed at 1989. Recently chemists use this ligand for enzyme models because it provides rich sulfur environment. Some chemists use PS3 to synthesize novel metal complexes. Others study the transmetalation of PS3 tin complexes with FeCl3. As a continuation of our long time interest in these tin complexes as alkylation reagents, this thesis reports the synthesis and characterization of the tin-PS3 complexes. Reactions using SnCl3Me or SnCl3Bu as metal sources when dissolved in DMSO gave DMSO adduct of PS3 tin complex while sublimation gave reductive elimination products with alkyl groups transferred onto sulfur atom. The butyl transferred product and its methyl analogous are similar in morphology but different in skeletal arrangement.
Reaction of SnCl4 with PS3 gave two different crystals after long standing. One is the hydrolysed product, [Sn(OH)(PS3)]2, with bridging hydroxyl groups and thiolate groups. The other is the product with oxidized ligand. Reaction of SnBr4 with PS3 gave analogous ligand-oxidized product. Reaction of two mole of SnCl3Bu with PS3 resulted in a bimetallic tin complex.
