1. (Thio)urea organocatalysis—what can be learnt from anion recognition? Thiourea is an organo-sulfur compound with formula SC(NH 2) 2. Fetching data from CrossRef. The tendency towards deprotonation increases with the acidity of the receptor and with the stability of the [HX2]− self-complex.

H-bond donating. Thus, the more acidic thiourea containing receptor deprotonates in the presence all the investigated anions except chloride, whereas the less acidic urea containing receptor undergoes deprotonation only … This significant difference might be attributed to the most compact and strong hydrogen bonding interactions in 5-FU urea … Separation or combination of non-covalently linked partners provides polymorphs of article provided that the correct acknowledgement is given with the reproduced material. Determination of thiourea based on the reversion of fluorescence quenching of nitrogen doped carbon dots by Hg2+. Urea and thiourea-based receptors are well known for their affinity to interact with anionic species or electron rich neutral molecules through hydrogen bonding provided by NH protons (Jia et al., 2016; Singh et al., 2014; Zhang et al., 2013, 2015).Their binding tendency can be modulated by changing the subgroups.

Thus, the more acidic thiourea containing receptor deprotonates in the presence all the investigated anions except chloride, whereas the less acidic urea containing receptor undergoes deprotonation only in the presence of fluoride, due to the high stability of [HF 2] −. It is structurally similar to urea except that oxygen atom is replaced by a sulfur atom. with the reproduced material.
