A novel dendrimer-type m-terphenyl substituent for the kinetic stabilization of highly reactive species

A novel m-terphenyl-based steric protection group (Bpq group) bearing a dendrimer-type framework was designed and successfully applied to the stabilization of the corresponding N-thiosulfinylaniline and arenesulfenyl iodide. The Bpq group was found to provide a very inert environment for the reactive functionality embedded in its cleft.
