Selective precipitation of alkyl dihalides using a newly synthesized water-soluble bisphosphorylpillar[5]arene. Issue 52 (23rd May 2016) - Cheng, Wenjin
Abstract : Bisphosphorylpillar[5]areneH2 binds strongly to alkyldiammonium ions and alkyl dihalides. The halogen bonds betweenH2 and alkyl dihalides lead to the rapid precipitation of the complex in water. Abstract : Bisphosphorylpillar[5]arenes (H1 andH2 ) were synthesized and used to study the host–guest complexation in organic solvents and water. The interactions between the guests and the phosphate of the hosts lead to strong binding towards alkyl dihalides and alkyldiammonium ions.H2 may be used to detect or separate alkyl dihalides in water due to the rapid precipitation of the complex.
