The metal‐dependent transition between intra‐ and intermolecular CH addition has been studied with the title reaction as example: With cis ‐H 2 Fe(pp 3 ), the cyclometalated compound 1 is formed, with cis ‐H 2 Ru(pp 3 ) the phenyl hydride 2 . A decisive factor might be the difference in size of the metal atoms, which leads to different crowding of the groups and different chelate ring strain ((pp 3 = P(CH 2 ) 3 PMe 2 ) 3 ).
