Synthesis,Crystal Structure and Fungicidal Activity of(E)-2-[(4-tert-Butyl-5-(4-methoxybenzyl)thiazol-2-ylimino)methyl]phenol

The title compound （E）-2-[（4-tert-butyl-5-（4-methoxybenzyl）thiazol-2-ylimino）methyl]phenol was synthesized by the reaction of 5-（4-methoxybenzyl）-4-tert- butylthiazol-2-amine with salicylaldehyde, and its crystal structure was determined by single-crystal X-ray diffraction. The crystal belongs to the monoclinic system, space group P21/c with a = 5.9362（8）, b = 11.5070（15）, c = 29.460（4）A, β= 97.326（3）°, V = 1995.9（5） A^3, Z = 4, F（000） = 808, C22H24N2O2S, Mr= 380.49, De= 1.266 g/cm^3, S = 1.031,μ = 0.181 mm^-1, the final R = 0.0474 and wR = 0.1441 for 4327 observed reflections （I 〉 2σ（I））. Intramolecular O-H…N hydrogen bond is observed in the crystal. The preliminary bioassay showed that the title compound exhibits 95% inhibition rate against Rhizoctonia solani at the test concentration of 500 mg/L.

HPLC测定邻苯氨甲基苯酚的氧化降解反应

建立高效液相色谱法（HPLC）测定邻苯氨甲基苯酚（PMP）氧化降解过程中的质量浓度变化。采用Hypersil ODS-C18反向色谱柱（4．6 mm ×250 mm ，5μm），流动相为甲醇-水（80∶20），检测波长243 nm ，流速1 mL/min ，外标法定量测定其质量浓度。液相测定结果表明，PM P质量浓度在5～100 mg/L范围内，被测溶液质量浓度与峰面积呈良好线性关系，平均加标回收率为93．22％～107．62％；试验精密度RSD＝0．20％（n＝8），重现性良好。该液相方法可用于邻苯氨甲基苯酚氧化反应的测定。
