Application

1.Boscalid is a broad-spectrum, systemic fungicide, it is effective in preventing and curing diseases resistant to sterol inhibitors, Bisimides, 1H-benzimidazole, pyrimidines, phenylamides, and methoxyacrylates. The product can be transported from the xylem to the top of the leaf tip and leaf margin of the plant Chemical book; it also has vertical Osmosis, which can be carried through the leaf tissue to the back of foliage's leaf; however, the product has very little redistribution in the vapor phase.

Synthetic method

1.Using o-chloronitrobenzene as raw material, Suziki reaction with P-CHLOROBENZOIC boric acid was firstly carried out, then reduced, and then condensed with 2-chloronicotinyl chloride to obtain the target product.

2.Using o-iodoaniline as raw material, the product was firstly reacted with 2-chloronicotinyl chloride and then Suzuki reaction with p-chlorophenylboric acid.
