The structure of the complex was unambiguously determined by X\u2010ray crystallographic analysis, which showed an almost linear Ru\u2212N\u2212C array. The electronic properties of the nitrogen atom were estimated by DFT calculations, and the results suggested double\u2010bond character of the Ru\u2212N bond. Kinetic studies and consideration of the substituent effect on the oxime ester led to the proposal of a reaction mechanism involving oxidative addition, which could proceed by N,O\u2010chelating coordination to the Ru center prior to N\u2212O bond cleavage. The obtained Ru ketimido complex could be transformed into a ruthenacycle by C\u2212H activation by a concerted metalation\u2013deprotonation mechanism in dichloromethane\/methanol. Ru ketimido complexes with a tethered alkyne or alkene moiety underwent chloroamination of unsaturated C\u2212C bonds followed by C\u2212H activation, which resulted in the formation of a ruthenacycle. Considering the LUMO of an isolated Ru ketimido complex, the chloroamination should proceed by a synchronous 1,3\u2010dipolar cycloaddition\u2010type mechanism. Insight into the character and reactivity of Ru ketimido complexes will be helpful for developments in the catalytic transformation of oxime esters.<\/jats:p>","DOI":"10.1002\/chem.201704102","type":"journal-article","created":{"date-parts":[[2017,9,18]],"date-time":"2017-09-18T10:08:05Z","timestamp":1505729285000},"page":"16892-16897","source":"Crossref","is-referenced-by-count":18,"title":["Generation
