A facile approach to complexes with PhEEPh (E = P, As) as ligand is opened up by the reaction of 1 with PhE(SiMe 3 ) 2 . Complexes 2 and 3 are formed by exchange of chlorine and Me 3 Si‐migration, respectively. In the reaction of 2 with CH 3 COCl, the diphosphene ligand is displaced by Cl ⊖ ; moreover, the Me 3 Si groups are substituted by CH 3 CO groups. Recrystallization of this compound leads exclusively to the meso ‐derivative 4 .
