• Tris(1,1,1,3,3,3-hexafluoro-2-propyl) phosphite (tris(1,1,1,3,3,3-hexafluoroisopropyl) phosphite) is a sterically hindered, weakly -g-donating and strongly -accepting ligand. it can be prepared by the reaction of lithium salt of 1,1,1,3,3,3-hexafluoro-2-propoxide with pcl3. it reacts with nucleosides to form deoxyribonucleoside 3α-bis(1,1,1,3,3,3-hexafluoro-2-propyl) phosphite units.tris(1,1,1,3,3,3-hexafluoro-2-propyl) phosphite (tris(1,1,1,3,3,3-hexafluoroisopropyl) phosphite) may be used in the following processes:
• Preparation of new phosphonylating and coupling agents for the synthesis of oligodeoxyribonucleotides
• Preparation of nucleoside h-phosphonate units
• Synthesis of tetrakis(1,1,1,3,3,3-hexafluoroisopropoxy)(phenylthio)phosphorane by reacting with 1,1,1,3,3,3-hexafluoroisopropyl benzenesulfenate
