Palladium(II) Schiff base complexes derived from sulfanilamides and aminobenzothiazoles

Schiff bases (HL) derived from sulfanilamides or aminobenzothiazoles add to Pd(OAc)(2) to give complexes of the type PdL2 (1-7) in moderate to excellent yields. Reactions of Schiff bases containing pyrimidine groups, however, gave several products arising from competing coordination of the pyrimidine nitrogen. Palladium complexes and Schiff bases have been investigated as antifungal agents against Aspergillus niger and Aspergillus flavus.
