S-(4-Methoxy­phenyl) 3-methyl­sulfonyl-2-oxoimidazolidine-1-carbo­thio­ate

In the title compound, C₁₂H₁₄N₂O₅S₂, the five ring atoms of the imidazolidine are nearly coplanar, the average deviation being 0.077 Å. The imidazolidine and benzene rings make a dihedral angle of 73.98 (10)°. The crystal packing is stabilized by weak intermolecular C—H...O hydrogen bonds.

2-Meth­yl-2-nitro­prop­yl methane­sulfonate

The title compound, C₅H₁₁NO₅S, has been obtained by reacting 2-meth­yl-2-nitro­propanol with methane­sulfon­yl chloride. The average S=O and S—O bond lengths are 1.414 (3) and 1.570 (3) Å, respectively. The mol­ecules are linked via C—H...O inter­actions, forming a three-dimensional network.
