Abstract

Reactions of bis-scandium bridged phosphinidene complex, [LSc(μ-PAr)]2 (L=MeC(NDIPP)CHC(Me)(N-CH2CH2N(iPr)2), DIPP=2,6-(iPr)2C6H3; Ar=2,6-Me2C6H3) (1), with pinacolborane, catecholborane, and 9-borabicyclo[3.3.1]nonane (9-BBN) are reported. Complex 1 reacts with pinacolborane and catecholborane to give scandium pinacolate (2) and catecholate (3), showing BO bond cleavage. These two scandium complexes contain an unusual [P(Ar)B(H)P(Ar)]2− dianion, which displays a μ-η2:η2 coordination model. On the other hand, reaction of complex 1 with 9-BBN affords the BH bond cleavage product, 1,3-diphospha-2,4-diboracyclobutane (4).
