Formation of platinum allyl and propargyl complexes from protonation of platinum enyne and diyne complexes
Protonation of (Ph3P)2Pt[eta2-HC=CC(CH3) =CH2] (2a) with excess HBF4¡¤Et2O produced the pi-allyl complex (Ph3P)2Pt[eta3-H2C=CC(CH 3)=CH2] +BF4- (3a-BF4) instead of a pi-propargyl complex. Reaction of excess CF3CO2H with 2a initially produced the analogous pi-allyl complex 3a-CF3CO2 which then added CF3CO2H across the vinylidene unit of 3a-CF3CO2 to give the pi-allyl complex (Ph3P)2Pt[eta3-CH3C(CF 3CO2)C(CH3)CH2]+CF 3CO2- (5a). Protonation of the platinum diyne complex [(p-CH3-C6H4)3P] 2Pt(eta2-CH3C?CC?CCH3) (7b) with HBF4¡¤Et2O at -73C initially produced the platinum hydride complex trans-[(p-CH3-C6H4)3P] 2-PtH(eta2-CH3C ? CC ? CCH3) +BF4- (9), which rearranged to the platinum pi-propargyl complex [(p-CH3-C6H4)3P] 2Pt[eta3-(CH3CH=)-CC ? CCH3]+BF4- (11) at -28C.
