FeCl3-Catalyzed 1,2-Addition Reactions of Aryl Aldehydes with Arylboronic Acids
摘要:
A novel protocol for the 1,2-addition reactions of electron-deficient aryl aldehydes with arylboronic acids using an inexpensive and environmentally benign iron catalyst is reported. In the presence of FeCl3 and 2-(di-tert-butylphosphino)biphenyl, 1,2-addition reactions of various electron-deficient aryl aldehydes with arylboronic acids provided the corresponding biaryl methanols in moderate to excellent yields.

A Rh-catalyzed directing group-free formal Suzuki–Miyauracouplingreaction was established between simple ketones and arylboronates based on activation of unstrained C−C bonds. The key to the success of this reaction is a nucleophilic addition/β-carbon elimination sequence that can activate the unstrained ketone carbonyl C−C bond without the assistance of directinggroup.
