(5), shows only a doublet for HB. Moreover, the vicinal H-lg9Hg coupling constants in Table I1 correspond to the observed data for 3-exo-acetoxy-exo-norbornyl-mercuric chloride (93.2 Hz'O) and 5 (114 Hz). Consequently, in both 2 and 3 the addition must be cis-exo, with the minor modification in the spectrum of the H3 proton apparently arising from some as yet unknown effect of the 7, 7-dimethyl substituents. The lifetime of such 1, 2-addition ...
