Synthesis, purification, and electron spin properties of the endohedral fullerene P@C 60 are reported. Highly enriched material could be obtained for the first time, making this molecule accessible for further experiments. We report the first successful chemical modification of P@C 60 via cyclo‐propanation to the C 2v symmetric monoadducts P@C 61 (COOCH 3 ) and P@C 61 (COOC 2 H 5 ). X‐band electron spin resonance data are presented and discussed. The phosphorus atom shows anisotropic hyperfine coupling in the modified fullerenes, in contrast to the unmodified case, and in contrast to similarly modified N@C 60 .
