Optically pure dicyano oxa[7]helicenes and helicene-like molecules have been prepared and investigated for their optical behavior. The isomers of the intermediate 4,4′-biphenanthrene-3,3′-diol were resolved by physically separating their 1-menthyl carbona
Pyrenedione-Catalyzed α-Olefination of Nitriles under Visible-Light Photoredox Conditions

Herein, we report a combination of pyrenedione (PD) and KOtBu to achieve facile alcohol dehydrogenation under visible-light excitation, where aerobic oxygen is utilized as the terminal oxidant. The resulting carbonyl compound can be easily converted to vinyl nitriles in a single-pot reaction, at 60 °C in 6-8 h. This environmentally benign, organocatalytic approach has distinct advantages over transition-metal-catalyzed α-olefination of nitriles, which often operate at a significantly higher temperature for an extended reaction time.
Manganese Catalyzed α-Alkylation of Nitriles with Primary Alcohols

The manganese(I) complex bearing a bidentate hydrazone ligand efficiently catalyzes the α-alkylations of nitrile using primary alcohols as alkylating agents. α-Functionalized nitriles were selectively obtained in good to excellent yields. The reaction is environmentally benign, producing water as the sole byproduct. Both benzylic and aliphatic alcohols could be used and functional groups were tolerated.
