The invention belongs to the technical field of organic chemistry, and particularly relates to a chiral sulfinamide monophosphine ligand based on a ferrocene skeleton and a preparation method for fullconfigurations of the chiral sulfinamide monophosphine ligand. Four optically pure chiral monophosphine ligands 1(S, R), 1 (R, R), 1 (S, S) and 1 (R, S) are obtained by using chiral sulfinyl imide with two configurations including R and S through two ways including a step-by-step method and a one-pot method. The synthesized sulfonamide chiral monophosphine ligand (denoted as HK-Phos) based on the ferrocene skeleton shows certain reaction activity and stereoselectivity as a chiral ligand in the research of asymmetric synthesis catalyzed by transition metal, and has potentialand wide application value.
