“…The 1-H cation 4d was also present (on average ca. 20%, its low-field signals being recorded first were weaker than the high-field signals): 1.57 (d, J = 7.0 Hz, 3 H, 1-Me), 2.69 (3 H, 3-Me), 2.96 (3 H, 6-Me), 4.05 (q, J = 7.0 Hz, 1 H, 1-methine), 7.57 (5 H, 2-Ph), 8.16 (d, J = 9.0 Hz, 1 , H-7), and 8.54 (d, J = 9.0 Hz, 1 H, H-8); pmr (CFg-COOD) 1.56 (3 H, 1-Me), 2.69 (3 H, 3-Me), 2.96 (3 H, 6-Me), 5.75 (5 H, 2-Ph), 8.16 (d, J = 9.0 Hz, 1 , H-7), and 8.54 (d, J = 9.0 Hz, 1 , H-8). This first recorded spectrum of the perchlorate of 2f, when retraced after a further 5 min, showed a marked increase in the concentration of the 1-H cation 4d (55%) and the emergence of the 3-H cation 3d (20%).…”

Preparation of encfo-Norbomylcarbonic-p-Methoxybenzoic Anhydride.-To a mixture of 3 g (0.017 mol) of erado-norbornyl chlorocarbonate and 2.61 g (0.017 mol) of p-anisic acid in 100 ml of dry ether at 0°was added, dropwise with stirring, 1.73 g (0.017 mol) of triethylamine in dry ether. The reaction mixture was stirred for 1 hr. The amine hydrochloride was filtered off and the ether solution was washed with dilute HC1, NaHCOa, and water, and then dried over anhydrous magnesium sulfate. Upon evaporation of the ether an oil was obtained. Attempts to induce the oil to crystallize met with failure.

“…7 In distinction to the mass spectral behavior of pyridine,8 however, the completely phenylated derivatives of pyridine, pyrazine, and 1,2,4-triazine were found not to scramble appreciably before decomposition. 4 We therefore thought it of interest to examine the extent of scrambling before fragmentation for several fully phenylated five-membered heterocycles containing nitrogen. This report is concerned with the scrambling in various fragment ions…”
