for the synthesis of quaternary carbon centres. Herein we report investigations into generation of tert-alkyl organoboron species using imidoyl chlorides as reagents in the organoboron cyanidation reaction. Although alkenyl side-products predominate in particularly hindered cases, tert-alkyl organoboron species can be successfully generated for less hindered examples.
产生叔烷基有机硼物质的方法有很高的要求,因为它们是合成季碳中心的宝贵中间体。在此,我们报道了在有机硼氰化反应中使用亚氨酰氯作为试剂对生成叔烷基有机硼物质的研究。尽管在特别受阻碍的情况下,烯基副产物占主导,但是对于受较少阻碍的例子,可以成功地产生叔烷基有机硼物质。
