Abstract:
The sterically hindered monomeric alkoxomagnesium compound [(Me 6 TREN)MgOCHPh 2 ][B(C 6 F 5 ) 4 ] ( 1 ) has been used to explore the role of magnesium alkoxides in ketone hydroboration. Experiments and DFT calculations are suggestive of a concerted reaction pathway traversing through a six‐membered transition state involving Mg−OCHPh 2 , B−H, and C=O bonds. Prompted by this hypothesis, we investigated the activity of [Mg(OCHPh 2 ) 2 ] ( 3 ), which exhibits turn‐over frequency reaching up to 59,400 h −1 under solvent‐free conditions and stability towards C=C, −OH, −NH 2 and −NO 2 . Due to the non‐existence of a metal hydride intermediate, such catalytic reactions will not get hindered in the presence of additional reactive functional groups.
