Reactions of symmetric resp. asymmetric ketene-derivatives with pseudophenalenones yield the symmetrically substituted pseudophenafulvenes 2 and 6, resp. a mixture of Z- and E-isomers 3a, 3b or only the E-isomer 4 and the Z-isomer 5.The steric influence of the substituents of the ketenes determine the reaction products. - Keywords: E-, Z-Isomers; Ketenes; Pseudohydroxyphenalenonefulvenes; Pseudohydroxyphenalenones
