Hydroformylation of Nitrogen-Containing Cyclic Olefins via "in-situ" Rhodium-Phosphine Catalysts

Hydroformylation of nitrogen-containing cyclic olefins (N-substituted nortropidines, N-methyl-1,2,3,6-tetrahydropyridine (THP)) with rhodium-PR3 catalysts prepared "in-situ" is reported.The nortropidines reacted rapidly when either trialkyl- or triaryl-type phosphines were used, and the regioselectivities were not significantly influenced by the nature of the phosphine.With the less basic THP the rates and selectivities were generally lower, and were influenced by the phosphine ligand and by the presence of added bases such as Et3N.
