Abstract

We have now studied the products of reaction of the next member of the series, 1, 7- dichloroheptane (7). In contrast with the clean reactions of dihalides 1, 3, and 5, the reaction of 1, 7-dichloroheptane produced a complex IH NMR spectrum (Figure 1) in which some of the chemical shifts were not readily attributable to known types of halonium or carbonium ion. Both the relative amounts and positions of some of the peaks seemed to vary from ...
