(12) All attempts to isolate 3 from the reaction medium either by us in a number of experiments or by others” have failed due to its extreme instability. However, 3 was characterized by'H NMR as already reported”,” and the unique formation of 3 was established by HPLC. New spectral data: NMR (Me2SO) 6 168.85, 151.77, 138.14, 137.65, 130.69, 123.11 (two car-bons), 116.51, 114.03, 91.37, 19.82; MS, 219 (MH', la), 202 (M-0, ...
