Publication date: Available online 26 September 2019Source: Journal of Organometallic ChemistryAuthor(s): Ke Cao, Cai-Yan Zhang, Tao-Tao Xu, Ji Wu, Li-Fang Ding, Linhai Jiang, Junxiao YangAbstractThe palladium catalyzed/counter ion tuned selective methylation of 9-amide-o-carboranes on B(4) and B(12) has been developed, and a series of o-carborane derivatives decorated with various groups have been synthesized with moderate yields. The in situ formed palladium species via counter ion exchange was proposed for the tunable B–H activation.Graphical abstractPalladium catalyzed/counter ion tuned selective methylation of 9-amide-o-carboranes on B(4) and B(12).
