A series of RuCp[OC6H3(CH2CH=CH 2-2)(R)](PPh3)n complexes (n = 2, R = H (1a); n = 1, R = 4-OMe (2b), 4-Me (2c), 4-Ph (2d), 4-Br (2e), 4-NO2 (2f), 6-OMe (2g), 6-Me (2h), 6-Ph (2i)) have been

Treatment of RuCP[OC6H4(CH2CH=CH 2)-κ1O: η2C,C′](PPh 3) (3c) with a Bronsted acid (HX) such as 2-al-lylphenol results in facile migration of a benzylic proton to the aryloxide, giving the (η3-allyl)ruthenium(II) complex RuCp[CH2-CHCH(C 6H4OH-2)-η3 C,C′,C″](PPh 3) (Ac). Thermodynamic and kinetic studies suggest that 3c associates with acid to give 3c · HX, and further addition of HX to 3c · HX causes the C-H bond cleavage reaction to give 4c.
