route to access an array of nitriles from aldehydes mediated by an oxoammonium salt (4‐acetylamino‐2,2,6,6‐tetramethylpiperidine‐1‐oxoammonium tetrafluoroborate) and hexamethyldisilazane (HMDS) as an ammonia surrogate has been developed. The reaction likely involves two distinct chemical transformations: reversible silyl‐imine formation between HMDS and an aldehyde, followed by oxidation mediated by the
一种可扩展,高产,快速的途径,可通过乙氧基铵盐(4-乙酰氨基-2-2,2,6,6-四甲基哌啶-1-氟肟酸四氟硼酸)和六甲基二硅氮烷(HMDS)介导的醛类中的一系列腈的进入已经被开发出来。该反应可能涉及两个不同的化学转化:HMDS和醛之间可逆的甲硅烷基亚胺形成,然后由氧铵盐介导的氧化和甲硅烷基化反应制得腈。废氧化剂可以容易地回收并用于再生氧铵盐氧化剂。
