Benzylammonium heptanoate–heptanoic acid (1/1) [PDF]
The title salt, C7H10N(+)·C7H13O2(-)·C7H14O2, is an unusual 2:1 stoichiometric combination of two carb-oxy-lic acid mol-ecules and one amine. Although there are crystal structures of a number of 1:1 complexes reported in the literature, 2:1 acid amine complexes are rather uncommon.

Using in situ GC-MS for analysis of C2–C7 volatile organic acids in ambient air of a boreal forest site [PDF]
An in situ method for studying gas-phase C2–C7 monocarboxylic volatile organic acids (VOAs) in ambient air was developed and evaluated. Samples were collected directly into the cold trap of the thermal desorption unit (TD) and analysed in situ ...

Ambient Hydrocarbonylation of Olefins Enabled by Visible-Light. [PDF]
A novel photo‐induced methodology for hydrocarbonylation has been established, resolving the inherent conflicts between competitive olefin and CO insertion in traditional methods that necessitate harsh conditions. Accordingly, an efficient and versatile hydrocarbonylation of olefins enabled by visible‐light irradiation under ambient conditions has been
