The title compound was obtained in 82% yield by the intramolecular cyc
lization of 4BrC(6)H(4)C(NSCCl3)[N(SiMe3)(2)] in CH2Cl2 at 23 degrees
C. It crystallizes in the triclinic system, space group P (1) over bar
, a = 7.957(3) Angstrom, b = 10.864(5) Angstrom, c = 5.625(1) Angstrom
, alpha = 95.94(3)degrees, beta = 97.79(2)degrees, gamma = 100.72(3)de
grees, V = 469.2(3) Angstrom(3), and Z = 2. The bond lengths of the pl
anar C2N2S ring indicate partial pi-delocalization.
