三光气法合成N-硝基-N-(2,4,6-三氯苯基)氨基甲酰氯

用三光气法合成了N 硝基 N (2,4,6 三氯苯基)氨基甲酰氯,并进行了结构表征。结果表明,用三氯甲基碳酸酯代替光气合成该化合物反应安全,条件温和,选择性好,收率高,消除了光气的危险性。

Crystal Structure of Diethyl 1-(p-toluenesulfonamido)-p-chlorophenylmethylphosphonate

The crystal and molecular structure of diethyl l-(p-toluenesulfon-amido ) - p chlofoPhenylmet hylphosphonate has been determined by X- ray d iffractionmethod- The crystal (C18,H23,ClNO5PS) is monoclinic with space group P21/c, a =8. 162(6), b= l8. O64(7), c= l4. 362(4) A, β=96. 29(3)°, V=2lO4. 7 A3, M.=431, 88, Z=4, Dx= l. 364 g/cm3, μ, = 3. 765 cm-1, F(000) = 904, R=0. 047 andRw=0. 0049 for 998 reflections with I>3σ(I). The 1H NMR spetrum of the title com-pound shows that the two ethoxy groups are magnetic nonequivalent, which is in agree-ment with its X-ray analysis result-
