The palladium(0) complexes of (E,E,E)-1,6,11-tris(arenesulfonyl)-1,6,11-triazacyclopentadeca-3,8,13-trienes deliver palladium to phosphanes with the generation of high concentrations of catalytically active species such as Pd(PPh3)2. After oxidation of the phosphanes, the palladium is reincorporated into the macrocycle, thus avoiding agglomeration and precipitation. These conclusions were reached by 31P NMR, 19F NMR, and electrospray ionization mass spectrometry studies of telomerization and Tsuji-Trost reactions. © Wiley-VCH Verlag GmbH & Co.
