Series of thiourea based tritopic receptor molecules were synthesized to be used as building blocks for halogen-bonded assemblies. Here 16 new receptor molecules were synthesized from two different 2,4,6-trialkyl-1,3,5-tris(bromomethyl)benzene starting materials via tris(isothiocyanatomethyl)benzene intermediates. The alkyl substituents in the benzene ring showed to be important for isothiocyanate group formation instead of competing thiocyanate group. The synthesis route allowed us to synthesize the isothiocyanate intermediates and further the receptor molecules without typically used and highly toxic thiophosgene. Synthesized receptor molecules were used to study their halogen bond acceptor properties with diiodotetrafluorobenzene donors by single crystal X-ray diffraction method. We were able to obtain five new crystal structures of halogen bonded complexes, in which all receptors showed two to four accepted C−I···S halogen bonds. The observed halogen bonds were highly directional and showed large variation in C=S···I acceptor angles indicating flexible acceptor properties of sulfur.

Halogen Bonding in Halothiophene Building Blocks
Koivuporras, Alisa; Mailman, Aaron; Guo, Hongshuang; Priimagi, Arri; Puttreddy, Rakesh (American Chemical Society, 2023)Thiophenes bearing monotopic and symmetric ditopic halogen substituents and asymmetric ditopic halogen and pyridine substituents that act as halogen bond acceptors were evaluated for their halogen bonding interactions with ... -
σ-hole interactions: the effect of the donors and acceptors nature in selenoureas, thioureas, halogenated species, substituted benzenes, and their adducts
Chernysheva, Maria (Jyväskylän yliopisto, 2021)This thesis is devoted to the investigation of σ-hole interactions and can be divided into two parts. The first part investigates the σ-hole interactions between seleno- and thioureas with halogenated species. It was ... -
Bamboo-like Chained Cavities and Other Halogen-Bonded Complexes from Tetrahaloethynyl Cavitands with Simple Ditopic Halogen Bond Acceptors
Turunen, Lotta; Pan, FangFang; Beyeh, Ngong Kodiah; Trant, John F.; Ras, Robin H. A.; Rissanen, Kari (American Chemical Society, 2018)Halogen bonding provides a useful complement to hydrogen bonding and metal-coordination as a tool for organizing supramolecular systems. Resorcinarenes, tetrameric bowl-shaped cavitands, have been previously shown to ... -
Halogen-Bonded Mono-, Di-, and Tritopic N-Alkyl-3-iodopyridinium Salts
