Photocatalytic Hydrogen Production from Hantzsch 1,4-Dihydropyridines by Platinum(II) Terpyridyl Complexes in Homogeneous Solution
摘要:
1,4-Dihydropyridines have been photocatalytically oxidized to pyridines by platinum(II) terpyridyl complexes with the generation of hydrogen in homogeneous solution. The hydrogen production proceeds in quantitative yield and with great catalytic turnover.

A novel visible-light-induced reaction for the reductive generation of synthetically important α-amino radicals proceeds via a π-π stacked ionic complex. Multiple π interactions stabilize the reactive intermediate, and neither a photocatalyst nor an initiator are required. This synthetic pathway enabled the synthesis of complex functionalized amines in high yield.
