Palladium catalyzed regioselective B–C(sp) coupling via direct cage B–H activation: synthesis of B(4)-alkynylated o-carboranes
Pd-catalyzed carboxylic acid guided regioselective alkynylation of cage B(4)–H bonds in o-carboranes has been achieved for the first time using two different catalytic systems. In the presence of 5 mol% Pd(OAc)(2) and 3 equiv. of AgOAc, the reaction of 1-COOH-2-R(1)-C(2)B(10)H(10) with R(3)SiC[tripl...
