WebPolychlorinated biphenyls (PCBs) are a group of industrial chemicals that have not been found to occur naturally. The generic structure of PCBs is shown in Figure 1, and consists of biphenyl chlorinated in one or more positions.The positions which can be chlorinated are numbered separately on each phenyl ring, using a prime (′) to differentiate between the … WebIn this study, we investigate the influence of chiral and achiral cations on the enantiomerization of biphenylic anions in n-butylmethylether and water. In addition to the impact of the cations and solvent molecules on the free energy profile of rotation, we also explore if chirality transfer between a chiral cation and the biphenylic anion is possible, …
