Complexes of [(dadi)Ti(L/X)]m That Reveal Redox Non-Innocence and a Stepwise Carbene Insertion into a Carbon-Carbon Bond
The addition of donors to (dadi)Ti(THF) (1-THF, dadi = [{-CH=N(1,2-C6H4)N(2,6-iPr2-C6H3)}2]n) afforded the adducts [(dadi)Ti(L/X)]m (1-L, m = 0, N2CPh2; m = -1, X = Cl-, N3-, OiPr-, CH3-, neoPe-, CH=CH2-, CCPh-, CCTMS-, H(D)-). In all adducts, the chelate was in the (dadi)4- redox state. For certain anions, evidence for intimate binding of the Li+ counterion was explored spectroscopically. Treatment of 1-THF with PhHCN2, yielded {PhC3H3(-NC6H4-2-NAr)2}Ti(THF) (3, Ar = 2,6-iPr2-C6H3), which contains a cyclopropanated dadi ligand. The mechanism was explored by calculations, and the addition of Ph2CN2 to 3 produced a nacnac derivative, {PhC(CHNC6H4-2-NAr)2}Ti(I?2-HNNCPh2) (4, Ar = 2,6-iPr2-C6H3), generated via hydrogen transfer from the cyclopropane.
