A compound useful for deoxygenation is provided. The present invention relates to compounds of the structure of formulas I and II. Wherein X is selected from the group consisting of O, S and NH, Y, A and B are independently selected from the group consisting of N and CH, and D, E and F are independently CH, Selected from the group consisting of N, O and S, the symbol --- represents a single bond or a double bond, and R1, R2 and R3 are independently a group consisting of H, an electron withdrawing group and an electron emitting group Chosen from. In other embodiments, these compounds are used as oxygen scavengers and in barrier compositions and articles. [Selection] Figure 1 |
