WebMar 27, 2024 · These ILs were synthesized by neutralizing the presynthesized trihexyl (tetradecyl)phosphonium hydroxide ( [P 66614 ]OH) with 4-substituted phenols (Scheme 11 ). The detailed synthesis process is as follows: First, [P 66614 ]Br in ethanol was passed through a hydroxyl ion exchange resin column at RT to give [P 66614 ]OH. WebFor many phosphonium ions, a very strong base (commonly butyl lithium) is required in order to do the deprotonation. The use of such strong base requires moisture-free conditions such as were required for doing the Grignard reaction.
