十五元三烯大环钯（0）配合物1，（E，E，E）-1-二茂铁磺酰基-6，11-双[（4-甲基苯基）磺酰基]-1，6，11-三氮杂环十五碳-3，8，13-三烯钯（0），是芳烃重氮盐与有机三氟硼酸钾之间Suzuki-Miyaura偶联反应的活性和可回收的催化剂。反应在有氧条件下在室温下进行，并且不添加碱。使用电喷雾电离质谱（ESI-MS）允许直接检测和鉴定的几个中间体，这进一步研究的铃木-宫浦反应的机理方面。((c)Wiley-VCH Verlag GmbH & Co. KGaA，69451魏因海姆，德国，2007）。
Fifteen-membered triolefinic macrocyclic palladium(0) complex 1, (E,E,E)-l-ferrocenylsulfonyl-6,11-bis[(4-methylphenyl)sulfonyl]-1,6,11-triazacyclopentadeca-3,8,13-trienepalla- dium(0), is an active and recoverable catalyst for Suzuki-Miyaura cross-couplings between arenediazonium salts and potassium organotrifluoroborates. The reactions were performed under aerobic conditions at room temperature and without added base. Use of electrospray ionization mass spectrometry (ESI-MS) allowed the direct detection and identification of several intermediates, which furthers the study of the mechanistic aspects of the Suzuki-Miyaura reaction.
