Claus' benzene
From Wikipedia, the free encyclopedia
Claus' benzene (C6H6) is a hypothetical hydrocarbon and an isomer of benzene [1]. It was proposed by Adolf Karl Ludwig Claus in 1867 [2] as a possible structure for benzene at a time when the structure of benzene was debated. The molecule can be described as a hexagon with carbon atoms positioned at the corners, with each carbon connected to its nearest ortho carbon and the two para carbons connected diametrically [3]. High strain energy makes its synthesis impossible.[4]
