Reaction Steps
The acetylenic carbinol which was obtained as described above under paragraph (b) was oxidised as described for its isomer in Example 18, paragraph (c). Thus, 1.38 g. of carbinol gave 0.9 g. (66%) of 2,6,6-trimethyl-1-tetrolyl-2-cyclohexene, b.p. 100°-105°/0.7 Torr. NMR spectrum (CCl4): 0.96 (6 H, d badly resolved), 1.52 (3 H, m), 2.0 (3 H, s), 5.57 (1 H, m), 2.66 (1 H, m) ppm (δ).
