Abstract

The present invention relates to intermediate compounds for the preparation of hydrido-tricyano-borate anions, their preparation and their uses.

First claim

1 .- 12 . (canceled)

13 . A compound of formula III
{[Me] + } 2 [B(CN) 3 ] 2−   III
in which [Me] + denotes an alkali metal cation.

14 . A process for preparing a compound of formula III according to claim 13 comprising reacting a compound of formula II
[Me 1 ] + [B(CN) 4 ] −   II

in which [Me 1 ] + denotes an alkali metal cation with an alkali metal [Me 1 ] in which the alkali metal [Me 1 ] and the alkali metal cation [Me 1 ] + are the same or different.

15 . (canceled)

16 . A process for using a compound of formula III according to claim 13 for preparing a compound of formula I-1
[Me] + [BH(CN) 3 ] −   I-1

in which [Me] + denotes the alkali metal cation,
comprising reacting a compound of formula II
[Me 1 ] + [B(CN) 4 ] −   II

with an alkali metal [Me],
where [Me 1 ] + denotes an alkali metal cation which is different or the same as the alkali metal [Me] resulting in the formation of a compound of formula III
{[Me] + } 2 [B(CN) 3 ] 2−   III

in which [Me] + denotes the alkali metal cation of the alkali metal, and
hydrolyzing the compound of formula III.

17 . A process for using a compound of formula III according to claim 13 for preparing a compound of formula I-1
[Me] + [BH(CN) 3 ] −   I-1

in which [Me] + denotes the alkali metal cation,
comprising hydrolyzing the compound of formula III.
