摘要

Experimental pryrolysis results of unsatured acetals with allyloxy structure us to postulate two different cyclic, 6-membered transition types: the one yields propenyl ehters, the other esters. These transpositions take place by acyclic, cyclic or semicyclic acetals (2-vinyl or 5- alcoylidene 1, 3-dioxans, 1, 3-dioxep 5-enes, 2-allyloxytetrahydropyrans). Cyclic acetals generally react at higher temperatures than linear ones. A series of original propenyl ...
