Abstract
Abstract The chloromethylation of calix[4]arene 1a and of the methyl ethers of calix[6]arene 1b and calix[8]arene 1c , using chloromethyl n-octyl ether and SnCl 4 in chloroform at room temperature has been performed in good yield for the first time. The chloromethylated products 2a–c have been used as intermediates to introduce on calixarenes phosphonic acid groups which render these macrocycles water soluble and potentially useful in Host Guest Chemistry.
