摘要:
The invention concerns a process for preparing nitrobiphenylene of formula (I) wherein m stands for 1 or 2, R means halogen, R' or OR', R' being a C-organic group which can carry groups which are inert in the reaction conditions, n stands for 0, 1, 2 or 3 and, if n is 2 or 3, the R groups can also be different. According to the invention, a chloronitrobenzene of formula (II) is reacted in the presence of a palladium catalyst and a base in a solvent with a phenyl boric acid (IIIa), one of its alkyl esters of formula (IIIb), R meaning C1-C6 alkyl, or one of its anhydrides. The compounds (I) are suitable as initial products for biphenylamines which are in turn intermediate products for fungicidal plant-growth substances.
摘要(中):
一种用于制备式(I),其中m是1或2的nitrobiphenyls方法中,R是卤素,R“或OR”,其中R“是一个C-有机基团,其可以携带在反应条件下惰性的基团,其中 n为0,1,2或3,且在n为2或3的情况下,基团R可以是不同的,由式(II)的氯硝基苯在钯催化剂的存在下和在碱反应 溶剂中与苯基硼酸(IIIA)式(IIIb)的烷基酯,其中,R <1>的含义C1-C6烷基,或其酸酐反应。 化合物(I)是作为中间体联苯胺类,这又是用于杀真菌的作物保护活性成分的中间体是有用的。
