Complexes of Borane and 1,3,5‐Triazinane‐Derived Carbenes

Abstract

Complexes of borane with six‐membered N‐heterocyclic carbenes derived from readily accessible 1,3,5‐triazinium salts are described. Similar to the widely used imidazolium‐type borane complex, the obtained complexes behave as agents for the hydrogen atom transfer in the Giese reaction and as sources of the boryl radicals in addition to imines. The amine nitrogen of these complexes does not undergo alkylation, but it can bind with another borane molecule.
