A facile synthesis of acetals and aldehydes from allylic ethers catalyzed by cobalt compounds
摘要:
Octacarbonyldicobalt has been found to be a very effective catalyst for both converting allylic ethers to their corresponding acetals in the presence of an alcohol and hydrolyzing allylic ethers to aldehydes. High yields(> 95%) were obtained in a very short reaction time under mild carbon monoxide pressure. Iron pentacarbonyl was also found to be an active catalyst but less effective than Co-2(CO)(8).
