The general formulas of these compounds are as follows:The strobilurin derivatives were synthesized from substitutedβ-keto esters (2) as starting material which were prepared from substituted ketones (1) and dimethyl carbonate. The ester (2) and methyl hydrazine or substituted amidine were dissolved in methanol and the mixture was heated to reflux to obtain the substituted 5-hydroxy-1H-pyrazole (3) or 4-hydroxy-pyrimidine (4). The title compounds were prepared by reacting the intermediates (3 and 4) with substituted halomethylphenyls which contain four active group under basic conditions.

Precursors of sulfates and alkali halides prepared in co-deposition process were mixed homogenously, annealed at high temperature and then formed CoO and NiO fibers, XRD, XPS, Raman and SEM were used to characterized the samples, the growth of these fibers might be a special LS mechanism: soluble precursors in molten salt decomposed gradually to form initial crystal nucleus and succeeding particles adhered to these nucleus and grew anisotropically in the special high temperature fluent medium, the higher decomposition temperature and solubility of the precursor are two key factors in this method, which are in favor of a longer growth process and result in larger sizes of the final metal oxides crystals.

以共沉淀方法生成硫酸盐与碱金属卤化物融盐的均匀混合前驱物，在高温下退火制备出了CoO和NiO的晶须，以XRD和XPS等对成份进行了分析，SEM分析了形貌特征，研究了不同前驱物热分解特性，认为本方法是一种简单的LS生长机制：可溶性前驱物于融盐中热分解后逐渐析出成核，后续的粒子附着在核上，在融盐环境下沿一定方向作准一维生长，其产物形貌之不同源于硫酸盐的高分解温度和在融盐中的可溶性，导致晶体生长过程中成核过程与生长过程竞争的结果对一般前驱物结果的偏移。
