Hydrogen-Bonded Anionic Host Lattices Constructed with Isocyanurate and Thiourea/Urea

Abstract

A series of seven inclusion complexes containing the isocyanurate ion, thiourea/urea, and selected quaternary ammonium ions as templates, namely, (CH

The Sodium (Iso)Cyanurates Nax[H3–xC3N3O3]·yH2O (x = 1–3, y = 0, 1): A Key‐Series for Understanding the Crystal Chemistry of Metal (Iso)Cyanurates

“…In that preceding study we encountered a variety of structural motifs, ranging from the well known isocyanurate ribbon uniformly found for monobasic salts to isocyanurate dimers and chains for dibasic salts as well as columns for tribasic salts, the latter of which are also known from various compounds synthesized via solid state approaches . In order to shed light on the relationship between degree of deprotonation, crystal water content and formed structural motif, we looked for a series of salts which does not incorporate other chemical species except metal cation, (iso)cyanurate anion and water, as it is well known that the structural pattern is mainly governed by intermolecular hydrogen bonds,, and found the Na x [H 3– x C 3 N 3 O 3 ] · y H 2 O series. Within this series, only Na[H 2 C 3 N 3 O 3 ] · H 2 O had been structurally characterized so far, showing the familiar ribbon motif …”

Integrated preservation and sample clean up procedures for studying water ingestion by recreational swimmers via urinary biomarker determination

“…From a scientific standpoint, the preservation and sample clean up approaches of our study may avoid association of cyanuric acid with urine matrix elements. The tendency for cyanuric acid to form such associations is suggested by earlier studies [16], and related, mechanistic association studies have been detailed recently [43][44][45]. Also, note that all steps are systematically integrated into the overall method.…”

N,N′‐Dimethylated Benzyloxytriazinedione: A Stable Solid Reagent for Acid‐Catalyzed O‐Benzylation

“…DMBOT is a stable crystalline solid, and thus it can be easily handled in air at room temp. MonoBOT has limitations in terms of reaction solvents and concentration; its solubility in aprotic solvents is low, probably due to its hydrogen‐bonding ability, similar to that of isocyanuric acid . In contrast, the solubility of DMBOT is much higher (details in Table S1 in the Supporting Information).…”
