Abstract

The present invention relates to a process for the preparation of indium(III) halodialkoxides of the generic formula InX(OR)2 where X=F, Cl, Br, I and R=alkyl radical, alkoxyalkyl radical, in which a composition (A) comprising an indium trihalide InX3, where X=F, Cl, Br and/or I, and at least one alcohol of the generic formula ROH, where R=alkyl radical, alkyloxyalkyl radical, is reacted with a composition (B) comprising at least one secondary amine of the generic formula R′2NH, where R′=alkyl radical, to the indium(III) halodialkoxides which can be prepared by the process and to their use.
