The initiation step in a deprotonation of CH-acidic compounds could be the formation of a complex between the organic precursor and the metalation reagent. This is the conclusion drawn from the reaction of Ph2P(O)CH3 with (Me3Si)2NLi, which yielded a stable dimeric adduct [(Me3Si)2NLi·OP(CH3)Ph2]2 with a central Li2N2 ring. MO calculations on the model system H2LiNLi·OP(CH3)2 support these experimental findings.
