Abstract

2-(4-(6) and 2-(6-Azulyl) ethyl (7) tosylates and nosylates were synthesized and subjected to buffered acetolyses. The~ RON~/~ ROT~ ratio for these two systems was found to be 2.1-3.3 compared to 10-13.5 found for this ratio for 2-phenylethyl, 2-(p-anisyl) ethyl, and ethyl tosylates and nosylates. The reduced value for this ratio for the derivatives of 6 and 7 was caused by elimination to the corresponding vinylazulenes competing with solvolysis, kt= ...
