synthesis of bis-imino nickel(II) NNN pincer complexes of the type [NiCl2C5H3N-2,6-(CHNArf)2}]; Arf=C6H3-2,3-F2 (1), C6H3-2,5-F2 (2), C6H3-3,4-F2 (3), C6H3-3,5-F2 (4), C6H2-2,3,4-F3 (5), C6H2-2,3,6-F3 (6), C6H2-2,4,5-F3 (7), C6H2-2,4,6-F3 (8), has been achieved and their reactivity in alkyl- and arylthiolation reactions of halobenzenes examined. The use of fluorinated substituents Arf on the imines has
[NiCl 2 C 5 H 3 N-2,6-(CHNAr f)2 }]型双亚氨基镍(II)NNN钳形配合物的合成;Ar f = C 6 H 3 -2,3-F 2(1),C 6 H 3 -2,5-F 2(2),C 6 H 3 -3,4-F 2(3),C 6 H 3 -3,5-F 2(4),C 6 H 2 -2,3,4-F 3(5),C 6 H 2 -2,3,6-F 3(6),C 6 H 2 -2,4,5-F 3(7),C 6 H 2 -2,4,6-F 3(8),已经实现并且检查了它们在卤代苯的烷基硫基和芳基硫基化反应中的反应性。在亚胺上使用氟化取代基Ar f可以调节这些配合物中的电子,并且已经分析了这些取代基和二硫化物在硫醇化反应中的影响。
