Methylselenized Glucose: Improvement of the Stability of Glucose-Supported Selenium via the End-Capping Strategy

Abstract

In this work, the end-capping strategy was adopted in selenized material production for the first time. Methylselenized glucose, as a new-generation selenized glucose product, was designed and synthesized under NaBH4-free conditions, avoiding the generation of hydrogen gas. In comparison with the reported works, the new method significantly reduced the production cost and enhanced production safety. The produced methylselenized glucose was an even more stable material and the low-valent Se in it was hardly oxidized by air, resulting in the elevated efficiency of the material serving as a practical Se fertilizer in Se-enriched crop planting.
