A carbon-carbon bond is formed between the α-carbons of the alkenyl ligands of the cis-bis(ethenyl)iridium complex [Ir(-CH=CH2)2(CH3CN)2 (PPh3)2]+ (2) to produce the η3-allyl complex [Ir(η3-CH3 CHCHCH2)(NCCH3)2 (PPh3)2]2+ (4) in the reaction of 2 with H+, and η4-butadiene complexes Ir(η4-CH2=CHCH=CH2)(A) (PPh3)2 (A = -CH=CH-+NEt3 (6), -C≡ CR (7)) in reactions of 2 with terminal alkynes (RC≡CH; R = H, Ph, and p-C6H4CH3) in the presence of NEt3. The deuterium labeling experiments suggest an initial attack of H+ on the β-carbon of an ethenyl ligand to lead to the C-C bond formation between the α-carbons of the two alkenyl groups of 2 to produce 4.
