A Mass Spectral Investigation of Water and Acetic Acid Elimination From 1- and 2-Indan Derivatives
Groenewold, G. S.,Gross, M. L.,Zey, R.
, p. 416 - 423 (1982)
Water and acetic acid eliminations from 1- and 2-indan derivatives have been investigated.Deuterium labeling, high resolution peak matching and the metastable peak analysis capabilities of a high resolution triple analyzer (E B E) mass spectrometer were employed to examine the eliminations.These experiments showed that water was lost from 1-indanol via 1,2 and 1,3 processes.These results contrast with those obtained for 1-tetralol, which specifically eliminates water in a 1,4 process involving the benzylic hydrogens.Water elimination from 2-indanol is preceded by a slow hydroxyl-benzylic hydrogen exchange and proceeds specifically 1,2.Water losses from both 1- and 2-indanol are characterized by large kinetic energy releases.Acetic acid elimination is shown to occur specifically 1,3 from 1-acetoxyindan and 1,2 from 2-acetoxyindan.

Direct Photorelease of Alcohols from Boron-Alkylated BODIPY Photocages

BODIPY photocages allow the release of substrates using visible light irradiation. They have the drawback of requiring reasonably good leaving groups for photorelease. Photorelease of alcohols is often accomplished by attachment with carbonate linkages, which upon photorelease liberate CO2 and generate the alcohol. Here, we show that boron-alkylated BODIPY photocages are capable of directly photoreleasing both aliphatic alcohols and phenols upon irradiation via photocleavage of ether linkages. Direct photorelease of a hydroxycoumarin dye was demonstrated in living HeLa cells.
Efficient Transfer Hydrogenation of Ketones using Methanol as Liquid Organic Hydrogen Carrier

Herein, we demonstrate an efficient protocol for transfer hydrogenation of ketones using methanol as practical and useful liquid organic hydrogen carrier (LOHC) under Ir(III) catalysis. Various ketones, including electron-rich/electron-poor aromatic ketones, heteroaromatic and aliphatic ketones, have been efficiently reduced into their corresponding alcohols. Chemoselective reduction of ketones was established in the presence of various other reducible functional groups under mild conditions.

Directly linked donor and acceptor arenes, such as phenanthrene/naphthalene/biphenyl and 1,3-dicyanobenzene were found to work as photoredox catalysts in the photoreactions of indene, 2,3-dimethyl-2-butene, and 4-methoxyphenylacetic acid. The new stable organic photocatalyst forms an intramolecular exciplex (excited complex) when irradiated in a polar solvent and shows redox catalyst activity, even at low concentrations. To the best of our knowledge, this is the first example of an intramolecular exciplex working as a redox catalyst.
