Alkylated Diaminodiphenylmethanes.-The following new propyl and butyl derivatives of 4, 4'- diaminodiphenylmethane were prepared with a view to converting them to the corresponding ketones by oxidation with chloranil as was done by Klieg12 with the tetramethyl derivative. However, this method of oxidation was not found applicable.
