Catalytic Effect of Reverse Micelles of a Cationic Surfactant on the Reaction of Calix[4]resorcinolarenes with 4-Nitrophenyl Bis(chloromethyl)phosphinate.
The presence of the aminomethyl fragment in the calix[4]resorcinolarene molecule favors its phosphorylation in chloroform. Reverse micelles of (2-hydroxyethyl)dimethylpentadecylammonium bromide catalyze this reaction, the catalytic effect being dependent on the length of the hydrocarbon chain of a calixarene and detergent concentration.
