✦ Synopsis

Photochemically induced intra-and inter-molecular reaction of 2,2 H -(1,2-phenylenedivinylene)dipyrrole (4a) led to a mixture of geometric isomers of 5 8) in 40% yield. The compounds were isolated and characterized spectroscopically and by catalytic hydrogenation to 5 7) were isolated in addition to 8. Under the same conditions N,N H -dimethyl-2,2 H -(1,2-phenylenedivinylene) dipyrrole (4b) undergoes only cis-trans-isomerization.
