Some Chemistry of Tris(pyrazoIyl)methylthiolate Derivatives

摘要

An efficient synthetic method for the preparation of TAS tris(pyrazolyl)methylthiolate (3) is reported. Nucleophilic exchange reactions with 3 gave (pyr)C(=S)SC(pyr)3 (4) and MeSC(pyr)3 (5). 5 acts as scorpionate ligand in [MeSC(pyr)3Cr(CO)3] (6), from the decomposition of TDAE~(2+) [SC(pyr)3Mo(CO)3~-]2 by SO2FC1 TDAE~(2+)[O=MoF4-F-Mo(=O)Cl4]~(2-) (8) was isolated. The X-ray structures of 3-6 and 8 are discussed.
