Diphos [R′ 2 C(CH 2 PR′′ 2 ) 2 ] and Triphos [R′C(CH 2 PR′′ 2 ) 3 ] are convenient ligand platforms in catalysis. Likewise, their Si counterparts, [R′ 2 Si(CH 2 PR′′ 2 ) 2 ] and [R′Si(CH 2 PR′′ 2 ) 3 ], are commonly employed as they have easier synthetic protocols towards the desired ligands. Alterations caused by C/Si exchange are often neglected and considered to have no significant influence on the properties of the complex; therefore, the differences are commonly not investigated. We show herein that C/Si backbone exchange does indeed have a significant influence on the stability and reactivity of metal complexes and should not be ignored.
