The Template Effect,exceeds the probability of linear polymer formation.. It therefore seems remarkable that many of the syntheses of macrocyclic polyethers which have been reported involve less than dilute if not very concentrated conditions.. The success of these large-ring intramolecular S.2 reactions is generally a

These compounds were prepared by a variety of routes and Pedersen offered a scheme in which he generalized the synthetic approaches he used. He designated the four principal methods “V”, “W”, “X”, and “Y”. The methods are discussed individually.

Quite a number of papers have been published on this subject since that time, especially dealing with the chemistry of phthalate., isophthalate., and ter

Perhaps these compounds would be easier and more economical to prepare and ultimately, of course, better in one respect or another than the molecules which inspired the research. In particular, the collateral developments of crown ether chemistry and phase transfer cata
