Claim:
A compound corresponding to the formula A-BH—NR 1 R 2 , in which: R 1 and R 2 are identical or different groups chosen from linear alkyl groups, branched alkyl groups, cyclic alkyl groups or arylalkyl groups, or else the R 1 and R 2 groups together form an alkylene group, and A represents: a) an optionally polycondensed aromatic group optionally carrying at least one substituent, b) an optionally polycondensed heteroaromatic group optionally carrying at least one substituent, c) a group chosen from vinyl, dienyl, polyenyl or alkynyl groups optionally carrying at least one substituent, said optional substituents of the groups defined in a), b) and c) being chosen from alkyls, alkoxys, aminos, dialkylaminos, halogens, nitrile groups, ester groups, amide groups, aldehyde groups protected in the acetal or thioacetal form, ketone groups protected in the acetal or thioacetal form, trialkylsilyl groups and dialkoxyboryl groups, with the proviso that A is different from a fluorenyl group when R 1 and R 2 together form an alkylene group, and A is different from a phenyl group when R 1 and R 2 each are an ethyl.
