Greener synthesis and biological application of organosilicon(IV) complexes derived from semicarbazone and thiosemicarbazone of 3-acetyl-2H-chromen-2-one by microwave irradiation
A new series of silicon(IV) complexes have been synthesized by adopting classical thermal- and microwave-irradiated techniques. The complexes are prepared by the reaction of dimethyldichlorosilane and triphenylchlorosilane with the sodium salts of 1-(1-(2-oxo-2H-chromen-3-yl)ethylidene)thiosemicarba...
