Abstract
The ‘normal’ three-coordinate iron–NHC complex [(IPr)Fe(N′′)2] (N″ = N(SiMe3)2) rearranges to its abnormal NHC analogue [(aIPr)Fe(N″)2] (6) on heating, providing a rare abnormal iron–aNHC complex, and the first such three-coordinate complex. The tert-butyl-substituted complex [(ItBu)Fe(N″)2] (4) undergoes a thermal decomposition that has not previously been observed in iron–NHC chemistry, resulting in the bis(imidazole) complex [(tBuIm)2Fe(N″)2] (7). A mechanism that involves consecutive C–H and C–N activation is proposed to account for the formation of 7.Keywords
