摘要

Experimental procedures for the reaction of cis, cis, ci. s, trans-cyclononatetraenide (ccct- CNT-; see 4) with bromomethyl acetate (la, R= H, X= Br) to give (cyclononatetraeny1) methyl acetate (Sa; 84% yield) as well as for the base-induced elimination of HOAc from 5a to give nonafulvene (6a; 44% yield) are described. Spectroscopic as well as chemical evidence for 6a and 6b is presented. An approximate high-field-NMR analysis of 6a and 6b has been ...
