Orthogonal π-bridges have been introduced into [2.2]paracyclophanes by the reaction of the pseudo-geminal bisacetylene with various monoacetylenes and nitriles. The reactions with bistrimethylsilylacetylene and dimethylacetylenedicarboxylate take place even in the absence of a catalyst. This procedure can incorporate not only aromatic but also heteroaromatic bridges, as in pyridine-annulated cyclophane. Georg Thieme Verlag Stuttgart.
