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(PPh 3 ) 2 . After oxidation of the phosphanes, the palladium is reincorporated into the macrocycle, thus avoiding agglomeration and precipitation. These conclusions were reached by 31 P NMR, 19 F NMR, and electrospray ionization mass spectrometry studies of telomerization and Tsuji−Trost reactions. (© Wiley‐VCH Verlag GmbH & Co.
