Abstract

(1969). sponding cations (If, 2+, 3+) were observed by extraction of CH2C12 solutions into FSO8H at-68". The data are summarized in Table I. The 2-methoxy-2-norbornyl cation (1+) showed two singlet methoxyl resonances in a 1: 4 ratio, whose mean position (6 4.68) is 1.6 ppm downfield (As) relative to the mean methoxyl position (6 3.08) in the covalent precursor 1. Such shifts are typical for methoxyls at-
