(8) Control experiments established that the observed rotations were not artifacts of the work- up or analysis. Moreover, when an achiral electrolyte, tetra-n-butylammonium perchlorate, was employed, no selectivity could be detected. Optical purities were calculated assuming a molecular rotation of 29,700'at 546 mfi for optically pure 1.'(9) J.-Y. Sun, Ph. D.
