Abstract

The title compound is a mono-thionated derivative of the diketopyrrolopyrrole red-pigment on the market. The crystal data are: C~18~H~12~N~2~OS, M
~r~ = 304.37, monoclinic, P__2~1~/n, a = 7.570(3) ร…, b = 4.869(3) ร…, c = 19.616(4) ร…, ฮฒ = 99.07(3)ยฐ, V = 714.0(6) ร…^3^, Z = 2, D
~x~ = 1.416, D
~m~ = 1.372 Mg m^โˆ’3^, graphite-monochromated Cu__K~ฮฑ~
, ฮป = 1.5418 ร…, F(000) = 316.00, ฮผ = 2.030 mm^โˆ’1^, T = 296 K, R = 0.073 for 890 reflections. The phenyl rings are twisted out of the planar heterocyclic system by about 6.3(7)ยฐ. The oxygen and sulfur atoms are not entirely on the plane of the heterocyclic system, but are located slightly below and above the plane by about 0.17(1) ร… and 0.09(1) ร…, respectively. The molecules are stacked alternately (upside down) in a herringbone fashion along the b-axis.

Some time ago we became interested in the synthesis of derivatives of Z-azetlnone (1). a lactam analogue of the "antiaromatic" hydrocarbon, cyclobutadiene. It seemed possible that a modification of the Reformatskii reaction, already used for the synthesis of Z-azetidinones, or g-lactams, 1 might y
