commercially available reagent, has been found to perform efficiently in the α-chlorination of aldehydes, including its catalytic asymmetric version, under very mild reaction conditions. Under our reaction conditions, this compound outperforms typical chlorinatingreagents for organic synthesis, facilitates workup and purification of the product, and minimizes the formation of toxic, chlorinated organic waste
已经发现三氯甲磺酰氯(CCl 3 SO 2 Cl),一种可商购的试剂,在非常温和的反应条件下,在醛的α-氯化反应中,包括催化的不对称形式,都能有效地进行醛的氯化反应。在我们的反应条件下,该化合物的性能优于用于有机合成的典型氯化试剂,有助于产品的后处理和纯化,并最大程度地减少了有毒的氯化有机废物的形成。

Very reactive organolithiumcompounds bearing an alkoxide function at the β-position with respect to the metal are obtained by direct metallation with lithium naphthalenide at low temperature of the corresponding lithium chlorhydrin salt; the reaction of these dianions with different electrophilic agents leads to the corresponding mono- and bi-functionalized compounds.
