26. The specific rates of solvolysis of the S-methyl- and S-ethyldibenzothiophenium salts have been studied in various solvents where the latter is reported to be more susceptible upon solvolysis. See: Kevill, D. N.; Anderson, S. W. J. Org. Chem. 1991, 56, 1845.

29. By the measurement of the NNE spectrum, the integral ratio of the two peaks at 58.1 and 59.3 ppm was estimated as 66:34, which might reflect on the selectivity in the ring-opening process (paths a and b in Scheme 2).
