Thermal cyclodehydrogenations to form 6-membered rings: Cyclizations of [5]helicenes
Xiang, Xue,Scott, Lawrence T.
, p. 3937 - 3940 (2008/02/11)
Flash vacuum pyrolysis (FVP) of [5]helicene induces a thermal cyclodehydrogenation to form benzo[ghi]perylene. Evidence is presented that supports an electrocyclization-rearomatization mechanism and is inconsistent with mechanistic alternatives involving the intermediacy of aryl radicals or carbenes in the helicene fjord region.

Dibenzochrysene dianion (32-) shows in its NMR spectrum a partitioning of charge.In the dianion most of the charge is located on the 'anthracene' moiety.These observations have been confirmed by MNDO calculations.In the calculations, the l
