METHOD FOR REGENERATION OF TETRAHYDROFURAN FOR USE IN ORGANOMAGNESIUM SYNTHESIS Russian patent published in 1997 - IPC

Abstract RU 2098414 C1

FIELD: organometallic compounds, chemical technology. SUBSTANCE: method involves purification and drying a solvent and its additional treatment with elements I-III groups periodic system chlorides that were taken at amount up to 1 wt. -% of solvent mass. Magnesium, calcium, barium, boron, aluminium, lithium, sodium and potassium chlorides were used as element I-III groups periodic system. The regenerated tetrahydrofuran is used in organomagnesium synthesis followed by synthesis of organovinylsilanes - -germans, -stannates. EFFECT: increased yield of silicon, germanium and tin vinyl derivatives. 2 cl, 1 tbl
