“…Two diastereoisomers were formed in a 1:1 ratio for 3-substitued carboranes (5 ba and 5 ca). [13,17] A significant electronic effect was observed (5 da-fa). For example, the 9,12-dimethyl carboranylated amine 5 da [18] was obtained in 76 % yield, whereas no reaction was observed for either 9,12-diiodo-o-carborane (1 e) [19] or 4,5,7,8,9,10,11,12-octamethyl-o-carborane (1 f).…”
