10.1039/C0CC01487G. Pretty. Very selective N-methylation, presumably discovered as a byproduct from a de
benzylation reaction. This must be known, but the selectivity is still very nice. - Matthew Todd
This is a typical de-
benzylation condition and i used many a times, never observed any alkylation. Table-2 entry-9. Proline to N-ethylproline in 85% yield? using 10%Pd/C in EtOH. Not done a reaction with a MeOD. Im not impressed. - Ahamed
secondary alcohols oxidized to the corresponding ketone without oxidants under the hydrogenation conditions, see this paper. http://pubs.acs.org/doi... - Ahamed
So MeOH ------> HCHO which then forms imine and this imine gets reduced under Pd/C, H2 conditions. The first part is strange. - Ahamed

I am continuously impressed by the publications that have appeared since Prof. Keith Fagnou's shocking passing a little over a year ago. The chemical community still mourns; it is clear from these post-mortem publications that Fagnou's - and his clearly dedicated and talented graduate students and post-docs - brilliance lives on. The chemistry that Fagnou has truly spearheaded, direct C-H functionalization, is a method of forming C-C, C-N, C-B, etc bonds without having to prepare one of the coupling partners, as in traditional transition-metal catalyzed cross-coupling reactions. Palladium, rhodium and ruthenium are commonly used catalysts in direct C-H functionalization reactions. Fagnou has published a great deal on arylation reactions of a wide variety of substrates and even a bit on direct
benzylation reactions. Some fairly recent reviews are linked in a previous post.A recent publication in Journal of Organic Chemistry (doi: 10.1021/jo102081a), "Predictable and Site-Selective... - Charles Daney
