摘要

The rate constants for the reaction of hydroxide ion with syn-and anti-9, lO-dioxabimanes (1, 5-diazabicy-clo [3.3. 0] octadienediones) correlate with the function [u (R,)+ 0.5~(R'')], p value of 3.0 (R,= CH, or H), and with [u (R,)+ 0.50 (Rill, p value of ca. 4 (R,= C1 or H). The p value for hydrolysis of lactones produced by photoisomerization of anti-bimanes is 3.7. Structures of the ring-opened hydrolysis products as l (2)-pyrazolinonylacrylic acids have ...
