SYNTHESIS AND SEVERAL TRANSFORMATIONS OF 1-ARYL ETHERS OF 1,2-PENTANEDIOL
Gasanov, V. S.,Alekperov, R. K.
, p. 1073 - 1077 (2007/10/02)
The reaction of 1-bromo-2-pentanol with substituted phenols in alkaline medium yield 1-aryl ethers of 1,2-pentanediol.The condensation of these ethers with α-chloroethers, carboxylic acid chlorides, and aromatic isocyanates gives the corresponding derivat
