Fig. 1: Synthesis of 13- to 16-vertex closo-carboranes and 16-vertex ruthenacarborane.
From: Synthesis and X-ray characterization of 15- and 16-vertex closo-carboranes
Synthetic route along with the molecular structures of 13-vertex closo-carborane (2b), 14-vertex closo-carborane (3b), 15-vertex closo-carborane (4b), and 16-vertex ruthenacarborane (5Ru). For clarity, in the X-ray structures, all silyl moieties and hydrogen atoms have been omitted. Orange, B; grey, C.
