PdCl2 in the presence of dppe or Xantphos(t-Bu) as the ligand is found to be an efficient catalyst for the N-alkylation of various primary and cyclic secondary amines using primary alcohols at 90–130 °C under neat conditions. Interestingly, good to excellent yields were achieved when more challenging secondary alcohols were used as alkylating agents at 130–150 °C. The reaction could be easily scaled

The present disclosure relates to methods for the hydroaminoalkylation of an olefin. Such methods can comprise reacting the olefin with a secondary amine in the presence of a catalyst of Formula (I). The present disclosure also relates to catalysts which can be useful in such methods. LxM(R1)y(I)
Silica supported palladium–NiXantphos complex is an efficient and high turnover heterogeneous catalyst for N-alkylation of amines and α-alkylation of ketones using alcohols under neat conditions at 120–140 °C following hydrogen borrowing strategy.
