Barton, Benita published the artciletrans-N,N’-Bis(9-phenyl-9-xanthenyl)cyclohexane-1,2-diamine and its thioxanthenyl derivative as potential host compounds for the separation of anilines through host-guest chemistry principles, COA of Formula: C19H14O2, the publication is Journal of Inclusion Phenomena and Macrocyclic Chemistry (2020), 97(3-4), 159-174, database is CAplus.
In this work, we investigate the potential of separating mixtures of the guest solvents aniline (ANI), N-methylaniline (NMA) and N,N-dimethylaniline (DMA) by means of host-guest chem. principles employing two novel host compounds, namely trans-N,N’-bis(9-phenyl-9-xanthenyl)cyclohexane-1,2-diamine (1,2-DAX) and trans-N,N’-bis(9-phenyl-9-thioxanthenyl)cyclohexane-1,2-diamine (1,2-DAT). These aniline solvents may exist in such mixtures since NMA and DMA are often prepared from ANI by alkylation methods, and reaction yields are seldom quant. Owing to their similar b.ps., ranging from 184 to 196°C, the more usual distillation techniques for their separation are challenging. After recrystallization experiments of the two host compounds from various combinations of these anilines, it was revealed that host-guest chem. certainly has the potential to serve as an alternative separation strategy for such mixtures Equimolar ANI/DMA solutions proved most successful, where both 1,2-DAX and 1,2-DAT showed near-quant. selectivity for DMA (90%). Both single crystal diffraction and thermal analyses were employed in order to understand the preferential behavior displayed by each host compound
