Polymorphism in Tetramethylammonium Selenocyanate – Crystal Structures of α‐, β‐, and γ‐[NMe4][SeCN]
This study reports the synthesis and crystallographic investigation of tetramethylammonium selenocyanate. The structures of α‐, β‐, and γ‐[NMe4][SeCN] are related to one another and also to the CsCl‐type. In the solid state, tetramethylammonium selenocyanate, [NMe4][SeCN], is polymorphic.

Radiolysis of ammonia-containing ices by energetic, heavy and highly charged ions inside dense astrophysical environments [PDF]
Deeply inside dense molecular clouds and protostellar disks, the interstellar ices are protected from stellar energetic UV photons. However, X-rays and energetic cosmic rays can penetrate inside these regions triggering chemical reactions, molecular ...

The synthesis of aromatic amino alcohols via a combination of an unspecific peroxygenase‐catalysed reaction, oxyfunctionalization, and addition of selected nucleophiles and electrophiles in a highly atom‐efficient manner was investigated. This study presents the design to aim for an atom‐efficient chemo‐enzymatic synthesis route towards aromatic amino ...

π‐Expanded Fluoranthenes as Chromophores With Tailored Properties
A series of π‐expanded fluoranthene scaffolds selectively functionalized with electron donors and acceptors were synthesized. The evolution of the structural, optoelectronic, and redox properties in relation to substitution and cyclization was comprehensively studied both in experiment and in theory. The results identify the compounds as highly tunable

Remote functionalization by tandem radical chain reactions [PDF]
Normal radical relay chlorination of cholestan-3α-ol directed by an attached m-iodobenzoate ester group affords a 9α-chloro steroid, but when the same reaction is conducted in the presence of an excess of CBr4 the product is a 9α-bromo steroid ...
