    • The invention relates to a method for producing substituted biphenyls (I) in which: R1 = nitro, amino or NHR3: R2 = CN, NO2, halogen, C1-C6 alkyl, C 2-C6 alkenyl, C2-C6alkynyl, C 1-C6-alkoxy, C1-C6 alkyl halide, C1-C6 alkylcarbonyl or phenyl; R3 = C1-C4alkyl, C2-C4 alkenyl or C2-C4 alkynyl; m = 1 or 2, and; n = 0 to 3. The invention is characterized in that a compound (II) is reacted with a diphenyl borinic acid (III) in the presence of a base and of a palladium catalyst selected from the group consisting of: a) palladium-trialkylphosphine or trialkylphosphine complex with palladium being zero in the oxidation state; b) salt of the palladium in the presence of triarylphosphine or trialkylphosphine serving as a complex ligand or; c) optionally, metallic palladium raised on substrates, in the presence of triarylphospine or trialkylphosphine in a solvent.
    • 本发明涉及一种制备取代联苯(I)的方法,其中:R1 =硝基,氨基或NHR3:R2 = CN,NO2,卤素,C1-C6烷基,C2-C6烯基,C2-C6炔基, C 1 -C 6烷氧基,C 1 -C 6烷基卤,C 1 -C 6烷基羰基或苯基; R3 = C1-C4烷基,C2-C4烯基或C2-C4炔基; m = 1或2, n = 0〜3。本发明的特征在于,化合物(II)与二苯基硼酸(III)在碱的存在下和钯催化剂的存在下反应,所述钯催化剂选自:a)钯 - 三烷基膦 或氧化态为钯的三烷基膦配合物为零; b)在作为络合配体的三芳基膦或三烷基膦存在下钯的盐; c)任选地,在三芳基膦或三烷基膦存在下,在溶剂中,在底物上升高的金属钯。
