When the resulting nitro compounds was reduced over 5% Pd/C catalyst, the nitro phosphinic acids required more catalyst that the esters nitro phosphinic acid, and dinitro compounds required more catalyst than mono-nitro compounds in the case of all nitro groups completely changed into amino groups.

用5％Pd/C作催化剂，将上述硝基物还原时发现，次膦酸形成的硝基物比次膦酸酯形成的硝基物需要更多催化剂才能使硝基全部还原成氨基；二硝基化合物比单硝基化合物需要更多的催化剂。
