Radical‐initiated P−H addition of (1 S ,2 S )‐C 5 H 8 (PH 2 ) 2 to cycloalkenes gave bis(secondary phosphanes), (1 S ,2 S )‐C 5 H 8 [P(H)C n H 2n−1 ‐ cyclo ] 2 ( n = 5−8), as mixtures of R P , R P′ , S P , S P′ , and R P , S P′ diastereomers. The three diastereomers of the peralkylated chiral P 2 ligand (1 S ,2 S )‐C 5 H 8 [P(CH 3 )C 8 H 15 ‐ cyclo ] 2 and its complexes with NiCl 2 , PdI 2 , and PtI 2 were prepared. The structures of [(1 S ,2 S )‐C 5 H 8 {P(CH 3 )C 8 H 15 ‐ cyclo ( R )} 2 NiCl 2 ] · [(1 S ,2 S )‐C 5 H 8 {P(CH 3 )C 8 H 15 ‐ cyclo ‐( S )} 2 NiCl 2 ],(1 S ,2 S )‐C 5 H 8 {P(CH 3 )C 8 H 15 ‐ cyclo ‐( R )} 2 PdI 2 , and (1 S ,2 S )‐C 5 H 8 {P(CH 3 )C 8 H 15 ‐ cyclo ‐( R )} 2 PtI 2 were determined by X‐ray diffraction.
