要旨

Reaction of the imidotitanium complexes [Ti(NtBu)(N2Npy)(py)] (1) and [Ti(N-2,6-C6H3iPr2)(N2Npy)(py)] (2) with phenyl acetylene and tolyl acetylene in toluene gave the corresponding {2+2} cycloaddition products [Ti(N2Npy){κ2-N(tBu)CHCR}] (R = Ph: 3, Tol: 4) and [Ti(N2Npy){κ2-N(2,6-C6H3iPr2)CHCR}] (R = Ph: 5, Tol: 6). Complex 6 is the first example of a key intermediate in the anti-Markovnikov addition of a primary amine to a terminal acetylene which has been structurally characterized by X-ray diffraction.
