2-(1,3-Dithian-2-yl­idene)-1-phenyl­butane-1,3-dione

The title compound, C(13)H(12)O(2)S(2), belonging to the group of dioxoketene cyclic S,S-acetals, was prepared from the corresponding dione in high yield. In the structure, the C=O and C=C bonds are not coplanar, with O=C—C=C torsion angles of −36.8 (4) and −21.0 (4)°. The dithian ring has a twisted...
