Abstract:
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 (NO)2 type of organosilicon (IV) complexes. The complexes are monomeric and non-electrolytic in nature. The coordination behaviour of Schiff babes through organosilicon (IV) has been investigated by IR, 1H, 13C & 29Si 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.
