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(??2-HNNCPh2) (4, Ar = 2,6-iPr2-C6H3), generated via hydrogen transfer from the cyclopropane.

Preparation method of mild diazomethane derivative

The invention discloses a preparation method of a mild diazomethane derivative. The preparation method comprises that EWG-substituted benzene sulfonyl chloride and hydrazine hydrate undergo a reaction to produce EWG-substituted benzene sulfonyl chloride, the EWG-substituted benzene sulfonyl chloride and aldehyde or ketone undergo a reaction to produce EWG-substituted benzenesulfonylhydrazone, and the EWG-substituted benzenesulfonylhydrazone, a base and an organic solvent are mixed and undergo a replacement reaction to produce a diazomethane derivative. The diazomethane derivative is not separated and purified and is further used for a tension small ring synthesis reaction and an insertion reaction. The benzene ring of benzenesulfonylhydrazone is introduced with an electron-withdrawing group EWG, and through electron effects and steric hindrance effects, the benzenesulfonyl group on the benzenesulfonylhydrazone is easily separated so that a diazomethane derivative is produced under very mild conditions and especially at the room temperature.
