overview

compound introduction

格氏试剂通常以溶液的形式使用,一般呈现为浅灰色至浅棕色透明溶液。它们一般以烷基卤化镁(RMgX)和二烷基镁(R2Mg)的中间态存在,是和复杂组分形成的平衡态混合物 (称为“Schlenk平衡”)。 其中的一些种类可能由于溶解度降低而产生沉淀,但这并不会影响它们的实际使用。 当出现沉淀时,请轻轻地摇晃瓶子使悬浮物充分分散后使用(如果沉淀物的量非常少,您可以使用悬浮液的上层清液)。特别是在冬天等寒冷的条件下,可能经常生成大量沉淀物。这种情况下,请用干燥的玻璃棒捣碎后使用。另外,您也可以将瓶子放进塑料袋后浸入40℃的水浴中使固体溶解(加热需要专业人员来操作,以防有安全隐患,请注意瓶子开启时有机溶剂的挥发)。用于 · 制备官能化无环烯基镁试剂/制备1,2-双酮 · 制备环化烯基和二烯基镁试剂 · 制备官能化三氮烯/制备咔唑 · 区域选择性官能化三取代吡啶 · 亲电子氨基化制备氨 · 在掩蔽酮和醛(使用易于脱保护的硅烷化氰醇)存在下,制备Grignard试剂 · 通过硫-镁交换制备苄型Grignards · 未保护芳香族和杂芳香族羧酸通过I-Mg交换官能化 · 未保护咪唑通过I-Mg交换官能化 · 吡啶合成 · 官能化环戊烯衍生物 · 制备2,3-官能化呋喃、苯并呋喃和噻吩 · 空间选择性合成取代环丙烷 Reagent used with CH3MgCl/LiCl to affect magnesium-halogen exchange on unprotected aryl carboxylic acids. Reagent for Selective Metalations Used for: 1.Preparation of functionalized acyclic alkenyl magnesium reagents/preparation of 1,2-diketones. 2.Preparation of cyclic alkenyl and dienyl magnesium reagents. 3.Preparation of functionalized triazenes/preparation of carbazoles. 4.Regioselective functionalization of trisubstituted pyridines. 5.Electrophilic amination for preparation of amines. 6.Preparation of Grignards reagents in the presence of masked ketones and aldehydes (using readily deprotectable silylated cyanohydrins). 7.Preparation of Benzylic Grignards via Sulfur-Magnesium exchange. 8.Functionalization via I-Mg Exchange of unprotected aromatic and heteroaromatic carboxylic acids. 9.Functionalization via I-Mg Exchange of unprotected imidazoles. 10.Pyridyne formation 11.Functionalization of cyclopentene derivatives. 12.Preparation of 2,3-functionalized furans, benzo
