WebIn addition, the 13 C NMR spectrum assured the absence of a carbonyl signal as well as the existence of a signal at δ 146.49 ppm correlated to C = N. Compound 11 was utilized as another way for the preparation of [1, 2, 4, 5]tetrazine and derivatives of [1, 2, 4, 5]tetrazepine via [5 + 1]- and [5 + 2]-annulation, respectively. WebFeb 19, 2024 · The very weak signal at 67 ppm may well arise from a small amount of tertiary chlorides. New signals appear in the δ = 125–135 ppm region. Based on liquid 13 C NMR , a clear correlation was found with 1 H signals between 5.39 and 5.50 ppm in the HSQC-DEPT135 spectrum of the dissolved product (Fig. S4†).
