2-Substituted 3,3-bis(alkylthio)- or 3-mercapto-3-alkylthioacrylonitriles and -acrylic acid esters

2-Substituted 3,3-bis(alkylthio)- or 3-mercapto-3-alkylthioacrylonitriles and -acrylic acid esters. Rudorf, Wolf D.; Augustin, Manfred (E.In this study， 62455-68-9 and 4640-66-8 are also used. Ger. ). Ger. (East) DD 119041 5 Apr 1976,4 pp. (German). (German Democratic Republic). CODEN: GEXXA8. CLASS: IC: C07C149-20. APPLICATION: DD 75-185403 14 Apr 1975. DOCUMENT TYPE: Patent CA Section: 25 (Noncondensed Aromatic Compounds) Section cross-reference(s): 24, 27, 28 Mercaptoles and hemimercaptoles R2C(CN):C(SR)SR1 [R = R1 = Me, R2 = 4-ClC6H4CO, 3,4-Cl2C6H3CO, 2-furoyl, 2-thenoyl, PhCH:CHCO, cyclohexylcarbonyl, 4-MeOC6H4CO; R = R1 = Et, R2 = 4-BrC6H4CO; R = R1 = 4-ClC6H4CH2, RR1 = (CH2)2, R2 = Bz; R = H, R1 = Me, R2 = 4-R3C6H4CO (R3 = H, Br, Cl, MeO), 3,4-Cl2C6H3CO, 2-furoyl] and EtO2CCBz:C(SMe)2 were prepd. by 3 methods. Thus, e.g., 0.2 mol NaH was added portionwise with stirring and cooling to 0.1 mol 3,4-Cl2C6H3COCH2CN and 0.1 mol CS2 in DMF, the mixt. stirred 2 h at room temp., and 0.22 mol MeI dropped into the mixt. to give 71% 3,4-Cl2C6H3COC(CN):C(SMe)2. Using 0.09 mol MeI gave 68% 3,4-Cl2C6H3COC(CN):C(SH)SMe. .
