Synthesis of Dimethyl (m-Carboran-9-yl)phosphonate and Dimethyl (p-Carboran-2-yl) Phosphonate by Palladium-catalyzed Cross Coupling of 9-I-m- and 2-I-p-Carboranes with Dimethyl Hydrogen Phosphite

Abstract

Dimethyl (m-carboran-9-yl)- and (p-carboran-2-yl)phosphonates were prepared by (Ph3)4Pd-catalyzed cross coupling of 9-I-m- and 2-I-p-carboranes with dimethyl hydrogen phosphite in the presence of triethylamine.
