Graphene oxide (GO)-catalyzed chemoselective thioacetalization of aldehydes under solvent-free conditions
摘要:
An efficient method for the synthesis of open chain, cyclic, and unsymmetrical dithioacetals from aryl/hetero-aryl/aliphatic aldehydes is described. The reaction is performed using graphene oxide (GO) as the catalyst under solvent-free and aerobic conditions. High chemoselectivity is observed in the reaction as aryl/alkyl ketones do not give thioketals under the condition. (C) 2014 Elsevier Ltd. All rights reserved.

Reversibility of dithioacetal bond formation is reported under acidic mild conditions. Its utility for dynamic combinatorialchemistry was explored by combining it with orthogonal disulfide exchange. In such a setup, thiols are positioned at the intersection of both chemistries, constituting a connecting node between temporally separated networks.
