Introduction of Alkyl- or Phenylseleno Group by the Ring Opening of Cyclic Ethers Using Dialkyl- or Alkylphenylselenium Dibromide and Sodium Borohydride
Abstract The reaction of dialkyl- or alkylphenylselenium dibromide with cyclic ethers in the presence of sodiumborohydride gave ω-hydroxyalkyl alkyl or phenyl selenides as the ring opening products of the cyclic ethers.
