L2NiCl2 (L = PEt3) gives the nickelacycle L2Ni(1,12-triphenylenediyl), which decomposes to a dimer (L2Ni2C36H20) containing two coupled triphenylene moieties with a new C−C bond. Thermolysis of the dimer completes the coupling, yielding a chiral tetraphenylene, while alkyne addition leads to cleavage of the newly formed C−C bond of the dimer and cycloaddition of the alkyne to the triphenylene fragment
1,12- dilithiotriphenylenediyl到L的另外2的NiCl 2(L = PET 3)给出nickelacycle大号2的Ni(1,12- triphenylenediyl),它分解为二聚物(L 2的Ni 2 Ç 36 ħ 20含有两个),其耦合具有新C-C键的三亚苯基部分。二聚体的热解完成偶联,产生手性四亚苯基,而炔烃的添加导致二聚体新形成的CC键的裂解以及炔烃与三亚苯基片段的环加成。
