Halogenated solvents such as dichloromethane,
dibromomethane, bromochloromethane, chloroform, and
carbon tetrachloride react with [(1-H-hydronaphthaelene)Mn(CO)3] (1) and pyridines (py‘) to give the halogeno
complex [Mn(CO)3(py‘)2X] (X = Cl, Br) and naphthalene.
The C−H and C−X cleavage reactions are dependent
upon the electronic and steric properties of the pyridine.
The structure of fac-[Mn(CO)3(4-Me-py)2Cl] (5b) has been
established by X-ray diffraction study.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
