General description

4-tert-Butylbenzyl mercaptan is a benzyl mercaptan derivative that is commonly used as a ligand for synthesizing metal clusters.

Application

4-tert-Butylbenzyl mercaptan (BBSH) may be used in the preparation of N-Me-aminopyrimidinone derivatives, which are potent state-dependent inhibitor of Nav1.7 (Nav= voltage-gated sodium channel). It may also be used to synthesize organic-soluble, atomically precise array of silver clusters via a novel approach based on the miscibility principle while avoiding the use of phase-transfer agents.
Reactant for:
  • Stereoselective thiourea-catalyzed sulfa-Michael addition
  • Nucleophilic substitution reactions
  • Urea-catalyzed trans-thioesterification
  • Sc-catalyzed Michael addition
  • Copper-catalyzed decarboxylative cross-coupling
