New scandium borylimido chemistry: synthesis, bonding and reactivity

Abstract:

We report a combined synthetic, mechanistic and theoretical study of the first borylimido complex of a rare earth metal, (NacNacNMe2)Sc{NB(NAr'CH)2} (25, Ar′ = 2,6-C6H3iPr2, NacNacNMe2 = Ar'NC(Me)CHC(Me)NCH2CH2NMe2). Thermolysis of the methyl-borylamide (NacNacNMe2)Sc(Me){NHB(NAr'CH)2} (18) generated transient imide 25 via rate-determining, 1st order methane elimination (KIE ca. 8.7). In the absence of external substrate, 25 underwent a reversible cyclometallation reaction (sp3 C–H bond addit...
