AbstractComplex [(p-cymene)Ru(η 1-O 2CCF 3) 2(OH 2)] mediated transformation of α-diazoacetamides ArCH 2N(C(CH 3) 3)C(O)CHN 2 to result in carbene insertion into the primary C-H bond exclusively, with the γ-lactam products being isolated in up to 98% yield. This unexpected reaction is striking in view of the presence of usually more reactive sites such as secondary C-H bonds in the substrates. DFT calculations based on proposed Ru-carbene species provide insight into this unique selectivity. © 2012 American Chemical Society.
