## 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
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
