Flusilazole and synthesis method thereof
The invention discloses flusilazole and a synthesis method thereof. The synthesis method comprises the following steps: putting magnesium powder into a Grignard reaction kettle; adding an organic solvent and uniformly stirring; cooling and adding p-fluorobromobenzene in one step; mixing and stirring; dropwise adding the p-fluorobromobenzene, and keeping heat and reacting; cooling and storing to obtain a p-fluorobromobenzene Grignard reagent; raising the temperature of the p-fluorobromobenzene Grignard reagent; dropwise adding methyl chloromethyl dichlorosilane and carrying out heat insulation;recycling an organic solvent under negative pressure to obtain a flusilazole intermediate, magnesium bromide and magnesium chloride; adding DMF (Dimethyl Formamide), stirring, cooling and centrifuging; removing the magnesium bromide and the magnesium chloride to obtain a DMF mother solution; dissolving triazole sodium salt into formamide; adding the DMF mother solution and reacting; recycling theDMF under negative pressure and distilling in vacuum; cooling to obtain the flusilazole. The content of the flusilazole is greater than or equal to 95.0 percent and the yield is 80 to 90 percent; thesynthesis method has the advantages of moderate reaction conditions, safety in operation, low equipment requirements, low cost, no wastewater and easiness for operation and implementation, and is suitable for large-scale production of enterprises.

Integrated palladium-catalyzed arylation of heavier groupa 14 hydrides
A convenient procedure has been developed for the preparation of Groupa 14 compounds by integrated palladium-catalyzed cross-coupling of aromatic iodides with the corresponding Groupa 14 hydrides in the presence of a base. The reaction conditions can be applied to the cross-coupling of tertiary, secondary, and primary Groupa 14 compounds. In most cases, the desired arylated products were obtained in synthetically useful yields. Even in the case of aryl iodides containing OH, NH2, CN, or CO2R groups, the reactions proceeded with good to high yields with tolerance of these reactive functional groups. A possible application of this method is the unique synthesis of a fungicidal diarylmethyl(1H-1,2,4-triazol-1-ylmethyl)silane derivative. A convenient procedure has been developed for the preparation of Groupa 14 compounds by integrated palladium-catalyzed cross-coupling of aromatic iodides with the corresponding Groupa 14 hydrides in the presence of a base (see picture). Application of this method in the synthesis of a fungicidal diarylmethyl(1H-1,2,4-triazol-1-yl-methyl)silane derivative is demonstrated. Copyright

Synthesis of Fungicidal (1H-1,2,4-Triazol-1-yl-methyl)silanes and -siloxanes
The synthesis of FlusilazoleTM (1a) was substantially improved by thorough exclusion of oxygen nucleophiles in the reaction of (chloromethyl)bis(4-fluorophenyl)methylsilane with sodium 1H-1,2,4-triazolide.New α,α-diaryl-α-(1H-1,2,4-triazol-1-yl-methyl)siloxanes 3 were obtained firstly from diaryl(1H-1,2,4-triazol-1-yl-methyl)silanols or -silanolates, which were prepared by different methods from the corresponding silanol hydrochlorides and further treated with functional, linear oligodimethylsiloxanes or secondly from α,α-diaryl-α-(chloromethyl)siloxanes and 1-(trimethylsilyl)-1H-1,2,4-triazole.The siloxane 4 containing a triazolylmethyl group and additionally silicofunctional coupling groups could be synthesized by hydrosilylation of an α-triazolylmethyl-ω-vinylsiloxane with triethoxysilane. - Key Words: Fungicides / Silanes / Siloxanes / 1,2,4-Triazoles
