Formation of platinum allyl and propargyl complexes from protonation of platinum enyne and diyne complexes

Protonation of (Ph3P)2Pt[η2-HC=CC(CH3) =CH2] (2a) with excess HBF4·Et2O produced the π-allyl complex (Ph3P)2Pt[η3-H2C=CC(CH 3)=CH2] +BF4- (3a-BF4) instead of a π-propargyl complex. Reaction of excess CF3CO2H with 2a initially produced the analogous π-allyl complex 3a-CF3CO2 which then added CF3CO2H across the vinylidene unit of 3a-CF3CO2 to give the π-allyl complex (Ph3P)2Pt[η3-CH3C(CF 3CO2)C(CH3)CH2]+CF 3CO2- (5a). Protonation of the platinum diyne complex [(p-CH3-C6H4)3P] 2Pt(η2-CH3C≡CC≡CCH3) (7b) with HBF4·Et2O at -73°C initially produced the platinum hydride complex trans-[(p-CH3-C6H4)3P] 2-PtH(η2-CH3C ≡ CC ≡ CCH3) +BF4- (9), which rearranged to the platinum π-propargyl complex [(p-CH3-C6H4)3P] 2Pt[η3-(CH3CH=)-CC ≡ CCH3]+BF4- (11) at -28°C.

Unexpected substitution reactions of bis(phosphine)platinum ethene complexes

Reaction of [Pt(C2H4)(PR3)2] (R = Ph or C6H4Me-4) with moderately bulky phosphines at low temperatures did not give the expected tris- or tetrakis-phosphine complexes. Instead, mixed-phosph

Kinetic generation of cis-C5H5(CO)2ReH2 from the reaction of C5H5(CO)2Re(μ-H)Pt(H)(PPh3) 2 with Diphenylacetylene

Protonation of K[C5H5(CO)2ReH] with CF3CO2H at -78°C produced a 65:35 mixture of cis-C5H5(CO)2ReH2 (cis-1) and trans-C5H5(CO)2ReH2 (trans-1). At 24°C, this mixture equilibrated to a 2:98 cis-1:trans-1 mixture. Reaction of C5H5(CO)2Re(μ-H)Pt(H)(PPh3) 2 (3-Ph) with diphenylacetylene at -9°C initially produced an 84:16 cis-1:trans-1 mixture. Photolysis of trans-1 in a methylcyclohexane glass at 10 K gave a 40:60 cis-1:trans-1 photostationary state. cis-C5H5(CO)2ReHD (cis-1-HD) has an unusual intermediate magnitude of JHD = 6.5 Hz, which suggested the possibility that cis-1 might be in equilibrium with C5H5(CO)2Re(η2-HD) (cis-1-η2-HD). However, it was not possible to detect measurable amounts of C5H5(CO)2Re(η2-H2) (cis-1-η2-H2) by IR spectroscopy.
