Metal Catalysts with Nonreducible Substrates in Organic Solvents

2 Metal Catalysts with Nonreducible Substrates in Organic Solvents 

A high degree of benzyl exchange was found to accompany the reductive deuteriation of 4-(4-fluorophenyl)methylpyridine with H2 catalyzed by Pd/C in various deuterated solvents, giving 4-(4-fluorophenyl)[ H2]methyl[ Hn]piperidine . 

Pyridines are known to be labeled C2 and C6 by a number of catalysts with heating under solvent-free conditions (see also Section 3.6). In the presence of small amounts of C H30 H at room temperature and under 22psi of for 24 h, Ru/C was shown to
