摘要:
Reactions of diethoxydimethylsilane with Schiff bases derived from the condensation of fur-furaldehyde, indole-3-carbaldehyde with alanine, glycine, valine, isoleucine and tryptophan in a 1:2 molar ratio give a new series of Me2Si ((N O) over cap)(2) type of organosilicon (IV) complexes. The complexes are monomeric and non-electrolytic in nature. The coordination behaviour of Schiff bases through organosilicon (IV) has been investigated by IR, H-1, C-13 & Si-29 NMR spectral studies. Schiff bases and their silicon complexes have also been screened for their antifungal activity. Several of these complexes were found to be quite active in this respect.
