Abstract
Treatment of [Mo(NAr)2Cl2(DME)] (Ar = 2,6-diisopropylphenyl; DME = 1,2-dimethoxyethane) with LiOC(OBut)CMe2 at low temperature affords the unexpected carbon-bound molybdenum(VI) enolate complex [Mo(NAr)2Cl{η2-C(Me2)CO2But}] 1; the novel α-aminoenolate derivative [Mo(NAr)2Cl{η2-CH(NMe2)CO2Et}] 2 is obtained under analogous conditions using LiNPri 2/Me2NCH2CO2Et; the structures of 1 and 2 confirm the carbophilic nature of the [Mo(NAr)2] core.Keywords
