A 2,6-dichlorophenol compound of formula (1):
1
wherein R represents a 3,3-dihalo-2-propenyl group or a benzyl group optionally substituted by halogen atom(s),
can be produced by making a phenol compound of formula (2):
2
wherein R has the same meaning mentioned above,
react with sulfuryl chloride in the presence of a secondary amine in high yield. The obtained 2,6-dichlorophenol compound of formula (1) is useful as intermediate for producing dihalopropene compounds having insecticidal/acaricidal activity.
公式(1)中的一种2,6-二氯酚化合物:其中R代表3,3-二卤-2-丙烯基或苄基,可以选择地被卤原子取代,可以通过使具有公式(2)的酚化合物:其中R具有上述相同含义,与亚砜氯在二级胺存在下反应,高产率地制备。得到的公式(1)中的2,6-二氯酚化合物可用作生产具有杀虫/杀螨活性的二卤丙烯化合物的中间体。
