Triphenylphosphine/2,3-Dichloro-5,6-dicyanobenzoquinone (DDQ)/[n-Bu₄N]OCN as a Useful System for the Efficient Conversion of Tetrahydropyranyl (THP) Ethers to the Corresponding Alkyl Isocyanates

Abstract

Triphenylphosphine/2,3-dichloro-5,6-dicyanobenzoquinone/tetrabutylammonium cyanate was used as an efficient system for the conversion of tetrahydropyranyl ethers to the corresponding alkyl isocyanates.

Keywords:

• Alkyl isocyanate
• 2,3-dichloro-5,6-dicyanobenzoquinone (DDQ)
• tetrahydropyranyl ether (ROTHP)
• triphenylphosphine (TPP)
