Application Guide for Palladium Catalyzed Cross-Coupling Reactions

Catalyst for:
• C,N-cross coupling of unprotected 3-halo-2-aminopyridines with primary and secondary amines
• Amination reaction
• N-arylation of aminophenols

General description

BrettPhos Pd G1 is a Buchwald first generation (G1) palladacycle precatalyst that can be used in cross-coupling reactions for the formation of C-C, C–N, C–O, C–F, C–CF3, and C–S bonds. The formation of the active Pd(0) species in the G1 precatalyst is easy to generate, requiring merely a deprotonation with a base. The resulting catalyst is very active, even at temperatures down to −40 °C, and can be used in a variety of cross-coupling protocols.

Palladium-catalyzed coupling of functionalized primary and secondary amines with aryl and heteroaryl halides: two ligands suffice in most cases

We report our studies on the use of two catalyst systems, based on the ligands BrettPhos and RuPhos, which provide the widest scope for Pd-catalyzed C-N cross-coupling reactions to date. Often low ca...
