Cyanogen halides are known substances for the cyanating reaction. There are a few evidences for bromination reaction too. On the other hand carbenes are known as very important substances due to their remarkable reactions. Unfortunately carbenes at room temperature are very unstable and there is not a simple method for preparation of them. In most cases the isolation is not possible. We have reported a new reliable and fast preparation method of almost stable carbenoids. The mechanism of the formation has been discussed.
氰化卤是众所周知的用于
氰化反应的物质,也有一些证据表明它们可用于
溴化反应。另一方面,由于其显著的反应性,卡宾被认为是非常重要的物质。不幸的是,卡宾在室温下极不稳定,并且没有简单的方法来制备它们。在大多数情况下,它们的分离是不可能的。我们报道了一种新的可靠且快速的制备几乎稳定的卡宾类似物的方法,并讨论了其形成的机制。
