Preparation of Tris(β-Diketonato)Indium and Tris(β-Ketoester) Indium from the Reaction in Non-Aqueous Solution

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).
