Formation and X-ray Structures of Eight- and Sixteen-Membered Rings (ArC) n N2 n (SPh) n [n = 2, Ar = 4-XC6H4 (X = Br, CF3); n = 4, Ar = 4-BrC6H4] and the Electronic Structures of (HC)2N4(SH)2 and (HC)2N4(SH)2 2-
Abstract
Optimum yields of heterocyclic products are obtained when the reaction of 4-XC(6)H(4)CN(2)(SiMe(3))(3) (X = Br, CF(3)) with PhSCl in a 1:3 molar ratio in CH(2)Cl(2) is carried out at -100 degrees C followed by the mixture being warmed to -70 degrees C for 16 h. Under these conditions the eight-membered rings (4-XC(6)H(4))(2)C(2)N(4)S(2)Ph(2) (1b, X = Br; 1c, X = CF(3)) are obtained in 64 and 80% yields, respectively, in addition to the purple …
