Abstract
Photolysis of tetracyclic azo compounds 15, readily available from [4+2] cy
cloaddition between 1,2,4,5-tetrazines and cyclopropenes, gives access to c
is- and traps-bis-sigma -homobenzenes 16 and 17. Thermal transformation of
the cis isomers 16 affords cis,cis,cis-1,3,6-cyclooctatrienes 18. Kinetic d
ata for these [sigma 2s+sigma 2s+pi 2s] cycloreversions are reported.
