Treatment ofCH 3Li or CH 3MgCl with TiCI 4 results in quantitative formation ofCH 3TiCl 3, a non-basic reagent which reacts chemo- and stereoselectively with carbonyl compounds It is considerably more reactive than the alkoxy analogue CH 3Ti(OCHMe 2) 3. This means that selective addition ...
而格式试剂指的是RMgX，是RX与Mg在无水乙醚中化合而成的。格氏试剂 Grignard reagent 一种金属有机化合物，通式RMgX(R代表烃基，X代表卤素)。1901年由F.-A.V.格利雅首次使用卤代烃RX与镁在醚类溶液中反应制得。又称格利雅试剂。格氏试剂广泛用于有机合成中，从RMgX可以制得RH、R—COOH、R—CHO...
Therefore, we searched for another reagent that would give the neutral iodo complex A via a different route. Moreover, we intended to vary the substituent on C3 in the oxametallacyclopentadienyl complex 2 by adding different nucleophiles to the intermediate A. In this study, we report on ...
