The new, fluorinated benzoxathiinopyrazole 4 and the hitherto unknown fluorinated benzoxathiinodihydropyridine 5 can be produced by reacting the title compound 1 with cyanoacetic hydrazide ( 3 ) in the presence of sodium acetate. The structures of the compounds 4 and 5 were confirmed with the help of spectroscopic techniques, and their respective paths of formation have been discussed. The structure of the ester 1 was extensively studied by single crystal X-ray analysis, then compared with that of the unfluorinated phenylsulfonate 2 . 相似文献

A new method for the synthesis of the unstable pentafluorosulfanyl isocyanide from N‐(pentafluorosulfanyl)(dichloromethanimine) was developed, thereby allowing for the study of its spectroscopic data. The structure of pentafluorosulfanyl isocyanide was determined by X‐ray crystallography at 113 K. The molecule possesses an almost linear S‐N‐C arrangement and an unexpectedly long S‐N bond. In addition, the structures of pentafluorosulfanyl cyanide, pentafluorosulfanyl isocyanate, pentafluorosulfanyl isothiocyanate, and N‐(pentafluorosulfanyl)(dichloro)methanimine were determined by single crystal X‐ray crystallography at low temperatures. 相似文献

Synthesis, Structure, and Coordination Chemistry of Isocyanoacetonitrile Isocyanoacetonitrile 1 was synthesized starting from aminoacetonitrile by the Ugi method. The structure and relative energies of 1 were calculated by ab initio methods (MP2/6‐31G**) in comparison with malonodinitrile and diisocyanomethane. 1 crystallizes on cooling below –14 °C forming a colourless solid, monoclinic, Pn, a = 614.9(2), b = 756.3(1), c = 786.4(3) pm, β = 98.99(4)°, Z = 4, R = 0.054, wR2 = 0.132, with two molecules representing the asymmetric unit. 1 polymerizes readily at ambient temperature forming a dark‐brown almost insoluble solid 2 . 1 can be stabilized by coordination to metal fragments. The metal complexes (CO)5M(CNCH2CN) ( 3 ) ( a , M = Cr; b , M = W), CpMn(CO)2(CNCH2CN) ( 4 ) and fac‐(CO)3W(CNCH2CN)3 ( 5 ) were synthesized and characterized by spectroscopic methods. The structures of 3 a , monoclinic, C2/c, a = 2481.4(7), b = 582.2(2), c = 2053.3(6) pm, β = 134.57(2)°, R1 = 0.0368, wR2 = 0.1001, and 4 , monoclinic, P21/a, a = 1223.7(2), b = 586.0(1), c = 1446.3(3) pm, β = 97.81(2)°, R1 = 0.0459, wR2 = 0.1190, were determined by single crystal X‐ray diffraction. 相似文献
