Preparation of the 15‐membered cycle ( E,E,E )‐1,6,11‐tris[(2,4,6‐triisopropylphenyl)sulfonyl]‐1,6,11‐triazacyclopentadeca3,8,13‐triene ( 8 ) is reported. This cyclic triolefin forms a stable Pd 0 complex 9 which catalyzes several cross‐coupling reactions and can be recovered. Anchoring to a polystyrene framework affords a solid version of the catalyst, which is recovered by simple filtration and reused without loss of catalytic activity.
