undergo peripheral cyclometalation with group 10 transition‐metal salts to afford the corresponding porphyrin‐based PCPpincercomplexes. The porphyrinic plane and the PCP‐pincer unit are apparently coplanar, with small strain. The catalyticactivities of the porphyrin‐based pincercomplexes at the periphery were investigated in the allylation of benzaldehyde with allylstannane and in the 1,4‐reduction
