✦ Synopsis

A new linker strategy for the attachment of aliphatic amines has been developed. Starting from Merrifield resin, an immobilized diazonium salt was prepared in two steps. Reaction of various amines gave rise to triazenes, which in turn were cleaved off upon treatment with mild acids. The triazenes have been proven to be base stable and were used in various types of transformations. The overall process is high-yielding and efficient.

Traceless linkers, which enable the attachment of arenes and alkanes to a polymeric support, have received increased attention in recent years. These anchoring groups allow chemical transformations on the polymer-bound molecules, which can be cleaved from the resin leaving no residual functionality
