It has now been found that a considerably higher total yield of
iminidibenzyl can be obtained by a different series of steps which are an
improvement on the process steps which up to now have been inadequate, by
oxidizing 2-nitrotoluene in the cold, i. e. between about 0-5℃,
with an alkyl formate or alkyl nitrite in the presence of an alkali alcoholated
to form the 2,2'-dinitrodibenzyl, reducing this by methods known per se to form
2,2'-diaminodibenzyl and finally heating the diphosphate of the latter compoundat about 280-320℃.
