Reactions of gallyliron complexes Cp*(OC)2FeGaR2 (R = Cl (1), Mes (2); Cp*, η5-C5Me5; Mes, 2,4,6-Me3C6H2) with pyridine in C6D6 afforded pyridine-stabilized gallyl complexes Cp*(OC)2Fe{GaR2(py)} (R = Cl (3), Mes (5a); py, pyridine). Photoirradiation of dichlorogallyl complex 3 in the presence of excess pyridine in benzene proceeded via the substitution of a CO ligand with another pyridine to give Cp*(OC)(py)Fe{GaCl2(py)} (4). However, photoirradiation of dimesitylgallyl complex 2 in the presence of excess pyridine gave gallane(pyridyl)iron complex Cp*(OC)Fe{(η1-HGaMes2)(η1-2-C5H4N)} (6a) via CO elimination and oxidative addition of the C-H bond at the 2-position of the gallium-coordinated pyridine. X-ray crystal structure anal. of 6a revealed the formation of a 3-center-2-electron (3c2e) bond in the Fe-H-GaMes2 fragment. Reaction of 4 with Me acrylate in toluene at 50°C resulted in substitution of the pyridine ligand on the iron atom with the C:C bond, giving Cp*(OC)(η2-CH2:CHCO2Me)Fe{GaCl2(py)} (7). In contrast, the reaction of 6a with Me acrylate in toluene at 100°C afforded vinyl iron complex Cp*(OC)2Fe(CH:CH2) (8) and 4-membered Ga2O2 cyclic gallane compound [Mes2GaOMe]2 (9) via cleavage of the Fe-Ga, C-O, and C-C bonds.
Organometallics published new progress about Bond cleavage. 576-83-0 belongs to class bromides-buliding-blocks, and the molecular formula is C9H11Br, Recommanded Product: 2,4,6-Trimethylbromobenzene.
