Abstract

The inference of single bicyclic intermediates in the competition of diglyme (or triglyme)For abbreviations see the table of [1].

with tetrahydrofurfuryl alcohol is confirmed by analysis of the linewidths. The dissymetric bicyclic species are characterized by linewidths increased markedly with respect to the pure solvents, without an accompanying change in the ^23^Na chemical shift. Conversely, the competition of glyme with the same alcohol involves three equi‐probable intermediates; that of tetrahydrofuran (or tetrahydropyran) is of greater conceptual complexity.
