A new strategy was developed for activation of C–N bond via formation of an amine–I2 charge-transfer complex, which facilitates the inert C–N bond activation via oxidative addition with Ni(0). This strategy has been successfully applied in the Ni-catalyzed carbonylation of benzylamines via direct insertion of CO into the C–N bond, which provided a straightforward and rapid approach to arylacetamides

for the allylic amination of internalalkynes with amines by using a polymer-supported triphenylphosphane-palladium complex [PS-TPP-Pd] as a highly active heterogeneous reusable catalyst was developed. The catalyst exhibited remarkable activity and is reusable over five consecutive cycles. The protocol was applicable for a variety of hindered and functionalized aromatic/ aliphatic amines and afforded
building on reductive coupling is a powerful method for the preparation of organic compounds. The identification of environmentally benign reductants is key for establishing an efficientreductive coupling reaction. Herein an efficient strategy enabling H2 as the sole reductant for the palladium-catalyzed allyl–allyl reductive coupling reaction is described. A wide range of allylamines and allylic alcohols
Pd(Xantphos)Cl2 has been identified as an efficient catalyst for the direct carbonylation of allylamines via C–N bond activation.
