The anion binding behaviour of a number of pyrrolylamidourea and thiourea compounds have been studied in DMSO solution. Mono-amidothioureapyrrole compounds were found to be deprotonated by basic anions such as fluoride, acetate, benzoate or dihydrogenphosphate with the structure of the deprotonated species elucidated by X-ray crystallography. 2,5-Bis-amidoureapyrroles were synthesized and found to be effective anion receptors for a range of putative anionic guests.
已经研究了许多吡咯酰胺脲和硫脲化合物在 DMSO 溶液中的阴离子结合行为。发现单酰胺硫脲吡咯化合物可被碱性阴离子(例如氟离子、乙酸根、苯甲酸根或磷酸二氢根)去质子化,并通过 X 射线晶体学阐明去质子化物质的结构。合成了 2,5-双-酰胺脲吡咯并发现它是一系列假定的阴离子客体的有效阴离子受体。
