Perchlorotriphenylene: a compound with severe molecular twisting?
摘要:
Perchlorotriphenylene has been reported several times in the literature. However, there is inconclusive evidence that this compound has actually been prepared. Severe molecular twisting to relieve steric interactions of ''ortho'' chlorines may preclude any stable existence. The compound is discussed in context with other severely twisted molecules, and methods are proposed for its synthesis.

Chlorination of triphenylene (1a) employing a mixture of aluminium trichloride and sulphur monochloride in sulphuryl chloride leads to rearrangement with formation of the title chlorocarbon (2), a new host, as main product. X-ray crystal structure analyses of the unsolvated spirocycle (2) as well as of its inclusion compounds with guests benzene and cyclohexa-1,4-diene are described.
