摘要：
Scandium terminal imido complex [(NNNN)Sc=NDIPP] (2; NNNN = [MeC(N(DIPP))CHC(Me)-(NCH2CH2NMeCH2CH2NMe2)](-), DIPP = 2,6-(Pr2C6H3)-Pr-i) reacts with 9-borabicyclononane (9-BBN) to give scandium borohydride [(NNNN(B)-H)Sc(N(H)DIPP)] (3; NNNN(B)-H = [MeC(N(DIPP))CHC(Me)-(NCH2CH2NMeCH2CH2N(Me)CH2(BBN)](2-)), and C(sp(3))-H bond borylation of the NNNN ligand occurs during this reaction. In contrast, the reaction between complex 2 and catecholborane (CatBH) gives scandium catecholate [(NNNN)Sc(Cat)] (4), and B-O bond cleavage happens during this reaction. Both 3 and 4 have been well-characterized including the single-crystal X-ray diffraction analysis. Reaction of 2 with bis(catecholato)diboron (CatB-BCat) also gives a B-O bond cleavage product.
