Isolation and stabilization of aryldiazonium cations with boron clusters

Abstract

Diazonium salts were found to be useful intermediates for many applications. Although few salts were isolated, they were found to be short lived. Charged boron cages have been known to be weakly coordinating anions. The cages were used to isolate short lived cations for characterizations and further reactions. In this study , we have facilitated dodecaborate dianion and carborate anion to isolate and characterize diazonium cations. With these cages, it was found that diazonium cation to be stable more than a month at ambient conditions.

Arildiyazonyum katyonlarının bor kümeleri ile izolasyonu ve stabilizasyonu

Abstract

Diazonyum tuzlarının birçok uygulama için yararlı ara ürünler olduğu bulundu. Birkaç tuz izole edilmesine rağmen, kısa ömürlü oldukları bulundu. Yüklü bor kafeslerinin zayıf koordine edici anyonlar olduğu bilinmektedir. Kafesler, karakterizasyonlar ve diğer reaksiyonlar için kısa ömürlü katyonları izole etmek için kullanıldı. Bu çalışmada, diazonyum katyonlarını izole etmek ve karakterize etmek için dodekaborat dianyon ve karborat anyonunu kolaylaştırdık. Bu kafesler ile diazonyum katyonunun ortam koşullarında bir aydan fazla stabil kaldığı görülmüştür.
