## Abstract MP2 and DFT calculations have been carried out for [__n__]circulenes for __n__=3 to 20 in order to predict the strain energy and topology of these cyclically condensed aromatic systems. To synthesise [4]circulene (**2**), 1,5,7,8βtetrakis(bromomethyl)biphenylene (**14**) was prepared fr

We have reinvestigated the anodic oxidation of 1,4~hydro-6.7-d;methoxy-4-(3.4-dimethoxy~l)-2-me~y~~u~o~-3(2H)~ne and found it to yield a new product 2.3.7.9-tetramethoxy-ll-(N-methylscetamido)i~[~,e]~cloh~~m-5~e. In order to investigate reactions of this rype 2-acyl-6.7-~imethoxy-4\_(3,4-dimethoxy~l
