Yield: 100%

Reaction Conditions:

at 60 - 100; for 1 h;Inert atmosphere;

Steps:

Synthesis of diisopropyl methylphosphonate S1
Triisopropyl phosphite (264 mL, 1.15 mol) was heated at 60 C. MeI (100 mL, 41.6 mol) wasslowly dropwised at this temperature. A exothermic reaction started, and heating wasdiscontinued until there was no more refluxing. The temperature was increased slowly to 100C and kept at the temperature for 1 h. The isopropyliodide was distilled off at ordinarypressure, and then the residue was distilled in vacuo (86-87 C, 14 torr) to quantitativelyafford S1 (124 g) as a colorless oil.
