METHOD OF OBTAINING 3-ARYL-1,5,3-DITHIAZOCANES Russian patent published in 2015 - IPC C07D285/38

Abstract RU 2538600 C2

FIELD: chemistry.

SUBSTANCE: invention relates to method of obtaining 3-aryl-1,5,3-dithiazocanes of general formula 1a-i R=H(a), m-CH₃(b), p-CH₃(c), o-OCH₃(d), m-OCH₃(e), p-OCH₃(f), o-NO₂(g), m-NO₂(h),p-NO₂(i). Essence of method consists in interaction of N¹,N¹,N⁷,N⁷-tetramethyl-2,6-dithiaheptane-1,7-diamine with arylamine (aryl = phenyl, m- and p-methylphenyl, o-, m- and p-methoxyphenyl, o-, m- and p-nitrophenyl) in presence of catalyst CuCl₂ in molar ratio N¹,N¹,N⁷,N⁷-tetramethyl-2,6-dithiaheptane-1,7-diamine:arylamine: CuCl₂ = 10 : 10: (0.3-0.7) at temperature ~60°C and atmospheric pressure in chloroform as solvent for 60-90 minutes. Output of respective 3-aryl-1,5,3-dithiazocanes constitutes 64-93%.

EFFECT: obtaining novel 3-aryl-1,5,3-dithiazocanes with high selectivity.
