A special type of photosynthesis of a helical compound is the irradiation of 1,1 -spirobi[benzindene] substituted with two tert. butyl groups 42) 58. 

The rate of dehydrocyclization increase with the number of aromatic rings in the molecule (19). The dehydrocyclization of alkylnaphthalenes can follow the same pathways as the cyclization of alkylbenzenes C5-dehydro-cyclization gives benzindans and benzindenes, while C6-dehydrocyclization yields anthracenes and phenanthrenes. In addition to these two pathways, a-substituted alkylnaphthalenes can cyclize to acenaphthenes and acenaphthylenes ... 

Propylnaphthalene can give two types of products by C5-dehydrocycli-zation dehydrocyclization at the pen-carbon atom of naphthalene gives 1-methylacenaphthene and 1 -methyl-acenaphthylene, while dehydrocyclization involving the /1-carbon atom of naphthalene gives 4,5-benzindan and 4,5-benzindene ... 

The C5-dehydrocyclization of 2-w-butylnaphthalene can give 4,5- or 5,6-methylbenzindans and benzindenes. Similarly, C6-dehydrocyclization can yield either phenanthrene or anthracene. The product distribution depends on reaction temperature and catalyst type. The C5-dehydrocyclization of l-(2-naphthyl)-butene depends on the acidity of the alumina, but...
