In situ generated superacid BF3–H2O catalyzed alkylation of p-quinols with diaryl carbinols leading to triarylmethanes
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%.
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.
