Process for preparing 2,3-dihydro-1,3-dialkyl-2,3-dialkyl perimidines and N,N-'-dialkyl-1,8-naphthalene diamines

Processes for preparing 2,3-dihydro-1,3-dialkyl-2,2-dialkyl perimidines and N,N'-dialkyl-1,8-naphthalene diamines are disclosed. The 2,3-dihydro-1,3-dialkyl-2,2-dialkyl perimidines are prepared by alkylating 2,3-dihydro-2,2-dialkyl perimidines with an alkylating agent in a water miscible organic solvent at room temperature to 80° C. in the presence of water and an inorganic base. N,N'-dialkyl-1,8-naphthalene diamines are prepared by hydrolyzing the 2,3-dihydro-1,3-dialkyl-2,2-dialkyl perimidines with strong aqueous acid in an aqueous organic solvent and removing a ketone by-product and the aqueous organic solvent by codistillation.

CONVENIENT SYNTHESIS OF 4-(TRANS-4 prime -N-ALKYLCYCLOHEXYL) BENZOIC ACIDS.

A convenient method of obtaining 4-(trans-4 prime -n-alkylcyclohexyl) benzoic acids from alkanoyl chlorides, cyclohexane and benzene is described. Homologous series of above mentioned acids and their nitriles with alkyl tail 2 to 10 carbon atoms were prepared and temperatures of their phase transitions were determined.
