Abstract Abstract: We describe a unique catalytic system with an efficient coupling of Ti- and Cr-catalyst in a reaction network that allows the use of [BH4]- as stoichiometric hydrogen atom and electron donor in catalytic radical chemistry. The key feature is a relay hydrogen atom transfer from [BH4]- to Cr generating the active catalysts under mild conditions.

The use of titanium as first row d-metal1 is particularly attractive for developing novel catalytic radical reactions because the metal frequently and efficiently shuttles between neighboring oxidation states through electron transfer (ET) with suitable substrates.
