New Extremely Deformed (Biphenylene)Hydrocarbon Skeletons The tetracyclic carbon skeleton 2‐oxo[3](1,8)biphenylenophane ( 4 ) was synthesized by cyclization of a mixture of the bis(bromomethyl) compounds 7a, b with p ‐tolylsulfonylmethyl isocyanide. 2‐Hydroxy[3](1,8)biphenylenophane ( 5 ) and the [3](1,8)biphenylenophane hydrocarbon 6 were obtained by reduction of 4 with LiAlH 4 and NaBH 4 , respectively. X‐ray analyses of 4 and 6 illustrate the dramatic deformation of bond lengths and angles in these molecules.
