✦ Synopsis

The cls,anti,cis isomer of tricyclo[3.1.0.0 2'4]hexane,2-5 first secured by Allred and Hlnshaw in 1968, may be obtained directly in 85% conversion through reaction of a solution of bicyclo[2.l.O]pent-2-ene6 in tetrahydrofuran with diazomethane in the presence of powdered cuprous chloride.

The transannular photocyclization of the cis,cis-cyclodecs-1,6+lienes to the tricyolo 5.3.0.02p6 --C 3 decane (1) may be explained due to the proximity in space of the two double bonds in the ~~hamnocks conformation I (2).

## Abstract The reversible isomerization of __cis__‐hepta‐1,3‐diene to __cis__‐2‐__trans__‐4‐heptadiene via a 1,5 hydrogen shift has been investigated kinetically at nine temperatures in the range of 475Β° to 531Β°K. Equilibrium is reached near 94% reaction. Some __cis__‐2‐__cis__‐4‐heptadiene is als
