The incorrect enantiomer was chosen for refinement in the X-ray crystal structure of 6.2CH2Cl2 (Figure 1) due to an error made during placement of the rigid group for camphor (ref 10). Refinement of the data using the mirror image of the structure shown in Figure 1 gave improved discrepancy indices of R = 0.061 and Rw = 0.076. A revised ORTEP drawing (with camphor rings now in agreement with those drawn in Scheme I) and new tables of X-ray data have been deposited as supplementary material. Supplementary Material Available: An ORTEP drawing and tables of positional and thermal parameters and bond distances and angles for 6.2CH2Cl2 (33 pages). Ordering information is given on any current masthead page.
