A new method was developed for the synthesis of N-nitroimidoyl chlorides O2N—N=C(R)Cl (R = SMe, Phth; Phth is phthalimide) by the reaction of O2N—N=C(R)SMe with SO2Cl2. The reaction of O2N—N=C(SMe)Cl with potassium phthalimide leads to the replacement of the Cl atom by the phthalimide moiety. The compounds O2N—N=C(Phth)Cl and O2N—N=C(Phth)SMe were studied by X-ray diffraction and quantum chemical methods. The C=N—N and NO2 groups in the O2N—N=C(Phth)Cl molecule were found to be completely orthogonal to each other. The explanation of this fact was proposed.
