• C-60
• P-31 NMR

With the aim to design a multidentate C-3v-symmetric trindane-based trisphosphine ligand 3 for Suzuki-Miyaura cross-coupling of 3-bromothiophene with phenylboronic acid, we observed the ability of this ligand to form an inclusion complex with buckyball C-60. Along with its catalytic activity, the pyramidal inversion at phosphorous atoms of 3 and the formation of 3@C-60 were investigated by H-1 NMR, P-31 {H-1} NMR and DFT methods.
