Synthesis and Structure of 14‐ and 15‐Vertex Ruthenacarboranes

Abstract

Adding corners: A metallacarborane with 15 vertices was prepared by reduction of 14-vertex carborane 1 to nido-carborane dianion 2 and subsequent reaction with [{(p-cymene)RuCl2}2] to give 3 (see scheme). The key to obtaining successively larger clusters is prevention of redox reactions (such as that to give 4).
