Abstract
Dimethyl substituted iminodibenzyls of the general formula: <FORM:0792615/IV (b)/1> are prepared by oxidizing a 2-nitroxylene in the cold with an alkyl formate or alkyl nitrite in the presence of an alkali metal alcoholate, reducing the dinitrodibenzyl so formed to the diamino compound and heating to about 280-320 DEG C. a mineral salt of the said diaminodibenzyl. In examples, o-nitro-p-xylene is reacted with isoamyl formate, or butyl formate, in the presence of sodium or potassium ethylate and in an inert solvent such as cyclohexane at a temperature below 5 DEG C., the 2 : 21-dinitro-4 : 41-dimethyldibenzyl is reduced by hydrogen in the presence of Raney nickel to the diamino compound, and this converted into the diphosphate salt which is then heated to 280-320 DEG C. to form 3 : 7-dimethyl-iminodibenzyl. By oxidizing 4-nitro-1 : 3-dimethyl benzene with amyl nitrite, and heating the mono hydrochloride of the diamine as above, 2 : 8-dimethyl-iminodibenzyl is formed.
