Eight novel N,N′-naphthalene acyl substituted aromatic acylamino thiocarbamides(Ⅱ1~Ⅱ8) were synthesized from aryl acylhydrazine(Ⅰ) and α-naphthalene acyl isothiocyanate, which was obtained by the reaction of potassium thiocyanate with α-naphthalene acyl chloride obtained from 2-naphthylacetic acid and thionyl chloride in anhydrous benzene.

A novel compound——N-naphthalene acylN′-substituted p-chlorobenzamido thiocarbamide was synthesized by reaction of p-chlorobenzamido hydrazine and α-naphthalene acyl mustard oil,which was obtained by potassium thiocyanate combined with α-naphthalene acyl chloride formed from α-naphthylacetic acid and SOCl2 in anhydrous benzene.
