Synthesis and Crystal Structures of Two Novel O, N-Containing Spiro Compounds
Crystals, 2016 Two novel O, N-containing spiro compounds, C16H16ClNO4 (1) and C16H16N2O6 (2), were prepared by reactions of monosubstituted benzenamine (substituent = –NO2, –Cl) and 1,5-dioxaspiro[5.5]undecane-2,4-dione in ethanol solution of trimethoxymethane.

Advanced Science, EarlyView.We developed a series of quinoxalinoquinoxaline (QQ) photosensitizers featuring high and tunable excited‐state reduction potentials (E(PC•+/PC*) = –1.76 to –2.05 V vs. SCE). Their hydrogen‐bonding interaction with carbonyl substrates enables selective single‐electron transfer events for selective nitrilization of 1° amides, offering a tunable ...
