本文是氯化乙烯镁制备的改进。新方法可防止氯乙烯的逃逸 ,简化操作。其重要的进步是革除 - 4 5℃的深度冷冻。将该格氏试剂用于合成乙烯基 β 紫罗兰醇和 6 甲氧基 1 乙烯基 萘满醇 ,证实它的用途。它们分别是异维甲酸及米非司酮的中间体。
This article is an improvement of the preparation of vinyl chloride magnesium. The new method prevents the escape of vinyl chloride and simplifies handling. Its major step forward is to get rid of - deep freezing at 45 ℃. This Grignard reagent was used for the synthesis of vinyl beta ionol and 6 methoxy 1 vinylnaphthaleneol, confirming its use. They are respectively isotretinoin and mifepristone intermediates.
