C,N-chelated triorganotin(IV) diesters of 4-ketopimelic acid and their fungicidal activity

Abstract

The set of four triorganotin(IV) diesters of 4-ketopimelic acid containing {2-[(CH3)(2)NCH2]C6H4}- as a C,N-chelating ligand was prepared. Their structures were studied by the help of IR, NMR and X-ray crystallographic techniques in the case of {{2-[(CH3)(2)NCH2]C6H4}SnPh2}(2)[(OOCCH2CH2)(2)C = O].

All these compounds are monomeric both in solid state and solution with five-coordinated tin atoms and medium strong intramolecular Sn-N connection. The antimycotical activity of these compound was studied and compared with the triorganotin(IV) derivatives of 4-ketopimelic acid and antimycotical drugs in clinical use.
