| 摘 要： | 1 INTRODUCTION Neonicotinioid insecticides as nicotinic acetyl-choline receptor inhibitors have attracted increasingattention because of its safety, low toxicity, wide andhigh activities[1, . A lot of new insecticides such as 2]imidacloprid, acetamiprd and nitenpyram have beencommercialized. It is found that most biologicallyactive nicotinic compounds contain 3-aminomethyl-pyridine moiety[3]. Due to their wide biological acti-vities, organic phosphorus heterocyclic compoundsplay an import…

| Abstract: | The crystal structure of the title compound (C17H19Cl2N2O3P, Mr= 401.21) has been determined by single-crystal X-ray diffraction. The crystal is of monoclinic, space group P21/n with a = 6.1648(6), b = 19.943(2), c = 15.268(2) (A),β = 99.220(2)°, V = 1852.8(3) (A)3, Z = 4, Dc =1.438 g/cm3, F(000) = 832,μ(MoKa) = 0.456 mm-1, the final R = 0.0622 and wR = 0.1586 for 3986observed reflections (I ＞ 2σ(I)). X-ray analysis reveals that the product is a thermodynamically stable cis isomer. The intramolecular hydrogen bond N(2)-H(2A)…O(1) is observed in the title compound. |
