Supramolecular catalysis analogue

In works/ the formation of the supramolecular systems based on branched and hydrophobized (alkyl-substituted) PEIs is revealed in both the absence and presence of cationic surfactants including those with hydroxyalkylated head groups. The latter are capable of specific interactions with other components of the systems, in particular, polymer and reagents. Hydrophobization of PEIs is found to result in a sharp increase in their solubilizing and catalytic efficiency. Besides, a marked increase in the catalysis occurs on transfer from conventional cationic surfactants to hydroxyalkylated analogues. By means of the optimization of the catalytic composition and reaction conditions a substantial 7(X)-2(XX)-fold acceleration of the phosphonate 1 is reached at neutral pH. ...
