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.
