Abstract
Three types of Sb~Ⅲ reagents were studied.They are:(1)the compounds containing mer-
capto group,(2)Caille and Viel reagents and(3)the compounds containing two phenolic
groups in adiacent positions.
It was shown experimentally that the first two types of reagents give reactions with very
low selectivities.Moreover,the selectivities could not be improved by merely varying the structure
of the organic compounds.
The diphenolic compounds seem to be the most hopeful reagents for Sb~Ⅲ.Their reactions
are considerably selective.Several classes of coloured compounds containing two phenolic groups
in adjacent positions were prepared.Some of them were found to be satisfactory reagents
for Sb~Ⅲ.
