The rhodium-catalysed 1,2-addition of arylboronic acids to aldehydes and ketones with sulfonated S-Phos
摘要:
The rhodium-catalysed 1,2-addition of arylboronic acids to aryl aldehydes has been accomplished in high yield using sulfonated S-Phos, a water-soluble biaryl phosphine ligand which allows for catalyst recycling. The catalytic protocol has also been successful in the challenging arylation of ketones. (C) 2009 Elsevier Ltd. All rights reserved.
