A unified approach for the synthesis of symmetrical and unsymmetrical dibenzyl ethers from aryl aldehydes through reductive etherification

الملخص EN

In this paper, we describe a simple and convenient conversion of aryl aldehydes to symmetrical dibenzyl ethers through reductive etherification.

Similarly, unsymmetrical dibenzyl ether was obtained from aryl aldehyde and TES-protected benzyl alcohol.

Triethyl silane with catalytic amount of InCl3 was found to be an efficient condition for the reductive etherification.

Moreover, it exhibits remarkable functional group compatibility with yield ranging from good to excellent.
