Thermolysis of cis,cis,trans-1-phenyl-1,3,5-heptatriene

Creator:: Tilton, Mary Lehman
Abstract:: Isomerically pure cis,cis,trans-1-pheny1-1,3,5- heptatriene was prepared and cyclized. Ring closure was followed by a 1,5 hydrogen shift, and the only product observed was 1-phenyl -6-methyl -1,3-cyclohexadiene. Rough first order rate constants for thermolysis and the hydrogen shift were determined. Kinetic estimates indicate that the report of disallowed product in a...
