(S)-T-BINAP is a versatile chiral organophosphorus ligand and has been used in several catalytic applications such as: 

1. Palladium catalyzed carbon-oxygen bond formation (Ref: J. Am. Chem. Soc., 1997, 119, 11108) 

2. Palladium-catalyzed α-arylation reaction of ketones (Ref: J. Am. Chem. Soc., 2000, 122, 6797)

3. Cu-catalyzed asymmetric conjugate reduction (Ref: J. Am. Chem. Soc., 1998, 120, 837)

4. Cu-catalyzed asymmetric dienolate addition to aldehydes (Ref: J. Am. Chem. Soc., 2003, 125, 11253)

5. Enantioselective conjugate reduction of lactones and lactams (Ref: Org. Lett., 2003, 5(20), 3691)

6. Enantioselective cycloaddition of allenylsilanes with α-Imino esters (Ref: J. Am. Chem. Soc., 2003, 125, 5644)

7. Catalytic Aldol reaction to ketones (Ref: Org. Lett., 2005, 7(22), 4955)

8. Rhodium catalyzed [2+2+2] cycloaddition reaction of alkenes and alkynes (Org. Lett., 2011, 13, 4692)

9. Iridium-catalyzed enantioselective C-H bond activation of 2-(alkylamino)-pyridine with alkenes (Ref: J. Am. Chem. Soc., 2014, 136, 8911)

10. Iridium-catalyzed regio-, diastereo-, and enantioselective tert-(hydroxyl)-prenylation of alcohols (Ref: J. Am. Chem. Soc., 2014, 136, 8911)

11. Rhodium-catalyzed cross cyclotrimerization (Angew. Chem., Int. Ed., 2014, 53, 2956)
