N-methyl-N-nitrosobenzylamine (Q) is not cyclo-(ortho-)palladated by Na2[PdCl4] but gives a complex of type [PdCl2O2]. In contrast N-Methyl-N-nitrosobenzylamine is readily ortho palladated to give the chloro-bridged complex [[graphic omitted]6H4}CI2](4a). This was converted into a mononuclear acetylacetonate (5a) and into species [[graphic omitted]6H4}ClL], L = PPh3( crystal structure determined),
N-甲基-N-亚硝基
苄胺(Q)未被Na 2 [PdCl 4 ]环-(邻位)palpalpalated,而是生成了[PdCl 2 O 2 ]型复合物。相比之下Ñ -甲基- Ñ -nitrosobenzylamine是容易邻palladated,得到
氯桥连络合物[[图形省略] 6 ħ 4 } CI 2 ](4a)中。将其转化为单核
乙酰丙酮化物(5a),并转化为种类[[图略] 6 H 4 } ClL],L = PPh 3(确定晶体结构),PMe 2Ph,或
吡啶,分别为(6a),(6b)或(6c)。每个
钯有两摩尔PPh 3时,Pd-NO键断裂,得到σ-芳基物质[Pd C 6 H 4 N(NO)CH 3 } Cl(PPh 3)2 ](7a),其晶体结构为这也已经确定。用1,2-双(
二苯基膦基)
乙烷(dppe),(4a)得到作为其四苯基
硼酸盐(8a)分离的离子[[省略图] 6 H 4 }(dppe)]
