The present application discloses a 3,3,3′,3′-tetramethyl-1,1′-spirobiindane-based phosphine ligand, an intermediate, a preparation method and uses thereof. The compound of phosphine ligand is a compound having a structure represented by formula I or formula II, or an enantiomer, a raceme, or diastereomer thereof. The phosphine ligand can be prepared via a preparation scheme in which the cheap and easily available 6,6′-dihydroxyl-3,3,3′,3′-tetramethyl-1,1′-spirobiindane is used as a raw material and the compound represented by formula III serves as the key intermediate. The new phosphine ligand developed by the present application can be used in catalytic organic reaction, in particular as a chiral phosphine ligand that is widely used in many asymmetric catalytic reactions including asymmetric hydrogenation and asymmetric allyl alkylation, and thus it has economic practicability and industrial application prospect.
