摘要
The reaction of bis(cyclohexylisocyanide) complex of Pd(II) with substituted benzo[d]thiazole-2-amines in the presence of triethanolamine as the base has lead to the formation of deprotonated C,N-chelated carbene complexes with a structure similar to that described previously for the products of the reaction with unsubstituted benzo[d]thiazole-2-amine. The complexes have been isolated and characterized using high-resolution mass spectrometry, IR and NMR spectroscopy (H-1, C-13{H-1}, H-1-H-1 COSY, H-1-H-1 NOESY, H-1-C-13 HSQC, H-1-C-13 HMBC). The resulting complexes have exhibited moderate antibacterial activity against sensitive strains of gram-negative bacteria E. coli (C600) and P. fluorescens (P218), gram-positive bacteria S. aureus (ATCC-25923) and B. subtillis (B-3142D) as well as fungi C. albicans (401/NCTC-885-653).
