- Abstract:
Racemizations of three series of non-planar 1-, 4- and 5-X-C7H5 cyclic conjugated allenes are investigate using ab initio HF, B3LYB and MP2 methods with a 6-31G* basis set (X= H, F, Cl, Br, I, OH, NH2, CN and NO2). These three differently substituted series of allenes are found to go through their corresponding planar 2-, 3- and 4-X-C7H5 singlet..
The access to the whole abstract and if available the presentation file is available to FIP members and to congress participants of that specific congress.
