Fluorinated β-diketones have been synthesized in high yield from the one-potreaction of silyl enol ethers with perfluoroalkyliodides initiates with Na2S2O4/NaHCO3, followed by treatment with diethylamine and acid hydrolysis.
氟化的β-二酮是由甲硅烷基烯醇醚与全氟烷基碘的一锅反应以Na 2 S 2 O 4 / NaHCO 3引发,然后用二乙胺处理和酸水解高产率合成的。

The present invention relates to a process for the preparation of thin silver nano-particles containing layers, which are produced directly on a substrate as part of a coating or printing process. The layers can show different colours in transmittance and reflectance. The invention further relates to decorative and security elements. When the layers are applied over a security element, such as a hologram, the obtained products may show different colours in reflection and transmission, an extremely bright optically variable image (OVD image). Depending on the thickness of the layer a more or less intensive metallic aspect appears.
