Abstract

The monoprotonation of diaza-12-crown-6 derivatives converts these macrocycles to hosts for short-chain alcohols: the association constant K(a) is as high as 47 M-1. For the neutral diaza crown ether, on the other hand, K(a) is only 1.1 M-1. X-ray structure investigations show that the alcohol (R = Me) is held in place by two hydrogen bonds (see right). R = Me, Et, nPr, nBu; R'= PhCH2, PhCH2CH2.
