Abstract

In this paper, a highly efficient and sustainable synthesis of triarylmethanes through the dehydrative coupling of p-quinols with diaryl carbinols is presented. The catalyst involved in this protocol is in situ generated superacid BF₃–H₂O from BF₃–OEt₂. Therefore, moisture has been used as an efficient initiator in this reaction system. A variety of diaryl carbinols and p-quinols have been investigated and found to be compatible to give the triarylmethanes in yields up to 96%.

原位生成超强酸BF3-H2O催化对喹啉与二芳基甲醇的烷基化反应生成三芳基甲烷

本文介绍了对喹啉与二芳基甲醇脱水偶联制备三芳基甲烷的高效、可持续方法。催化剂为BF3-OEt2原位生成的超强酸BF3-H2O。因此，在该反应体系中，水分被用作有效的引发剂。对多种二芳基甲醇和对喹啉进行了研究，发现它们的相容性使三芳基甲烷的产率高达96%。图形抽象

期刊介绍： Journal of Chemical Sciences is a monthly journal published by the Indian Academy of Sciences. It formed part of the original Proceedings of the Indian Academy of Sciences – Part A, started by the Nobel Laureate Prof C V Raman in 1934, that was split in 1978 into three separate journals. It was renamed as Journal of Chemical Sciences in 2004. The journal publishes original research articles and rapid communications, covering all areas of chemical sciences. A significant feature of the journal is its special issues, brought out from time to time, devoted to conference symposia/proceedings in frontier areas of the subject, held not only in India but also in other countries.
