Formation of the tetranuclear, tetrakis-terminal-imido Mn4IV(NtBu)8 cubane cluster by four-electron reductive elimination of tBuNNtBu. The role of the s-block ion in stabilization of high-oxidation state intermediates†
Abstract
Mn4IV(μ3-NtBu)4(NtBu)4 is obtained from a previously reported asymmetric MnIV/V–Li–(NR)(N) cluster by the removal of Li from the starting cluster by ion metathesis, which triggers reductive elimination of azo-tert-butane to give a tetranuclear heterocubane cluster.
