An Efficient Method for the Ether Forming Reaction between Alkyl Diphenylphosphinate and Alkoxytrimethylsilane by the Promotion of Trimethylsilyl Triflate

The trimethylsilyl triflate promoted reactions of alkyl diphenylphosphinates with alkoxytrimethylsilanes in chloroform, 1,2-dichloroethane or 1,2-dichloropropane, proceeded smoothly to give the corresponding ethers in good yields.
