Protonated cyclopropanes. X. Studies on the deamination of n-butylamine-1-14C and the decomposition of 3-(n-butyl-1-14C)-1-phenyltriazene

Abstract: The HNO2 deamination of n-butylamine-1-14C (1-NH2-1-14C) in aqueous HClO4 gave a n-butyl-14C alcohol (1-OH-14C) with about 0.7% scrambling of the label from C-1 to C-2, and a sec-butyl-14C alcohol (2-OH-14C) which showed extensive scrambling between C-1 and C-4, as well as small amounts of rearrangement of the label into C-2 and C-3. Analysis of the data suggested that about 2.5% of the 2-OH-14C product could be derived from equilibrating protonated methylcyclopropane intermediates. The HClO4 catalyzed decomposition of 3-(n-butyl-1-14C)-1-phenyltriazene (1-NNNHPh-1-14C) gave the unrearranged 1-OH-1-14C and a 2-OH-14C which showed only about 17–18% scrambling from C-1 toC-4. It is suggested that the different results observed in the deamination and the triazene decomposition may be due to a more ready initial formation of an ion pair in the triazene decomposition.

Novel photolytic triazene polymer

Abstract: The invention belongs to the technical field of the laser-induced forward transfer, and particularly relates to a novel photolytic triazene polymer. The provided triazene polymer has the novel structure, and is photolytic. The light absorption peak wave length thereof is more than 380 nm. The damage to cells caused by an ultraviolet source can be effectively avoided, and the potential requirement of applying the laser-induced forward transfer technology to the biomedical science experimental research can be satisfied. In addition, the triazene polymer has high purity and good solubility, can be decomposed into small pieces during the photolysis process, and decomposed into a gaseous product in the melting plume. The cellular layer cannot be polluted, and a solid melting product kept on the surface of the cellular layer can be taken away. An additional cleaning step is not needed.
