The chemical properties of alicyclic heterocycles are similar to those of the corresponding chain compounds. Compound: [Ir(dtbbpy)(ppy)2]PF6, is researched, Molecular C40H40F6IrN4P, CAS is 676525-77-2, about Selective Radical-Radical Cross-Couplings: Design of a Formal β-Mannich Reaction, the main research direction is radical cross coupling cyclic ketone imine photoredox catalysis organocatalysis.Category: copper-catalyst.
A direct β-coupling of cyclic ketones with imines has been accomplished via the synergistic combination of photoredox catalysis and organocatalysis. Transient β-enaminyl radicals derived from ketones via enamine and oxidative photoredox catalysis readily combine with persistent α-amino radicals in a highly selective hetero radical-radical coupling. This novel pathway to γ-aminoketones is predicated upon the use of DABCO as both a base and an electron transfer agent. This protocol also formally allows for the direct synthesis of β-Mannich products via a chemoselective three-component coupling of aryl aldehydes, amines, and ketones.
