Methylation of aromatic amines and imines using formic acid over a heterogeneous Pt/C catalyst

We describe here a commercially available Pt/C catalyst capable of catalyzing the methylation of anilines and aromatic imines with formic acid in the presence of a hydrosilane reductant. Both primary aniline and secondary aniline can be methylated. The advantage of this newly described method includ...

Description
Summary:We describe here a commercially available Pt/C catalyst capable of catalyzing the methylation of anilines and aromatic imines with formic acid in the presence of a hydrosilane reductant. Both primary aniline and secondary aniline can be methylated. The advantage of this newly described method includes operational simplicity, high TON, ready availability of the catalyst, and also good functional group compatibility. Methylation of anilines and aromatic imines has been achieved by using a heterogeneous Pt/C catalyst with formic acid in the presence of a hydrosilane reductant.
