  Alkyne Insertion into the Ru−C Bond of a Four-Membered Metallacycle. Insertion Rate and Reaction Pathway

  摘要：

  The insertion of HOCH2C drop CH (ha) into the Ru-C bond of Ru-II(RL1)(PPh3)(2)(CO)Cl, 1, has afforded Ru-II(RL3)(PPh3)(2)(CO)Cl, 3, which has been structurally characterized. Insertion rates in CH2Cl2-MeOH for ha as well as for PhC drop CH (pa), which inserts similarly into 1 affording Ru-II(RL2)(PPh3)(2)(CO)Cl, 2, are proportional to the product of the concentrations of alkyne and methanol. The insertion rate of ha is nearly 5 times faster than that of pa, and for a given alkyne the rate increases as R becomes more electron-withdrawing (OMe < Me < Cl). A reaction model implicating the adduct 1 . MeOH, which binds and activates the alkyne via displacement of MeOH, is proposed.
