Abstract
Anhydrous indium chloride in non-aqueous solution reacted with β-diketones (H-dik) or β-ketoesters (H-etac) in the presence of amines or sodium cyanate to give the corresponding indium chelate compounds of the type In(dik)3 or In(etac)3 in high yield, where H-dik = CH3cOCH2COCH3 (Hacac), CH3COCH2COC6H5 (Hbzac), C6H5COCH2COC6H5 (Hdbzm), and H-etac = CH3COCH2COOC2H5 (Hetac).
