A series of ionic (mono‐/di‐)phosphines ( L2 ,  L4 , and  L6 ) with structural similarity and their corresponding neutral counterparts ( L1 ,  L3 , and  L5 ) were applied to modulate the catalytic performance of RuCl 3  ⋅ 3H 2 O. With the involvement of the ionic diphosphine ( L4 ), in which the two phosphino‐fragments were linked by butylene group, RuCl 3  ⋅ 3H 2 O with advantages of low cost, robustness, and good availability was found to be an efficient and recyclable catalyst for the alkoxycarbonylation of aryl halides. The  L4 ‐based RuCl 3  ⋅ 3H 2 O system corresponded to the best conversion of PhI (96 %) along with 99 % selectivity to the target product of methyl benzoate as well as the good generality to alkoxycarbonylation of different aryl halides (ArX, X=I and Br) with alcohols MeOH, EtOH,  i ‐PrOH and  n ‐BuOH. The electronic and steric effects of the applied phosphines, which were analyzed by the  31 P NMR for   1   J  31  P‐  77  Se  1  J  measurement and single‐crystal X‐ray diffraction, were carefully co‐related to the performance RuCl 3  ⋅ 3H 2 O catalyst. In addition, the  L4 ‐based RuCl 3  ⋅ 3H 2 O system could be recycled successfully for at least eight runs in the ionic liquid [Bmim]PF 6 .
