Amidinato silylene complexes for bond activation and catalysis
This thesis primarily describes the development of amidinato silylene complexes for the purposes of bond activation and catalysis. Firstly, a paramagnetic dimeric amidinato cobaltosilylene was demonstrated to catalyze the regioselective C–H functionalization of arylpyridines by alkynes. It can also...

| description | This thesis primarily describes the development of amidinato silylene complexes for the purposes of bond activation and catalysis. Firstly, a paramagnetic dimeric amidinato cobaltosilylene was demonstrated to catalyze the regioselective C–H functionalization of arylpyridines by alkynes. It can also catalyze Kumada-type cross-coupling reactions. Next, an amidinato silicon(I)–iron(II) dimer was shown to be active in the catalytic hydroboration of carbonyl compounds in the absence of auxiliary reducing agents. A silylene boronium cation then exhibited reversible aliphatic C–H bond activation, the first of its kind. Lastly, an amidinato amidosilylene performed the challenging B–H activation. |
