The First Discovery of Intramolecular-Coordination Bonds in Cyclometalation Reactions,c acid esters with tinfoil based on IR spectra data in 1966. The stereoisomers of these reaction products were resolved into two kinds of stereoisomers by the use of mixed solvents, and each of the two structures of these stereoisomers was determined by X-ray diffraction studies in 1968 and 1969, respectively.

Halbleiter und Fotoelektrochemiehave resulted in the publication of a large number of articles, since organometallic intramolecular-coordination five-membered ring compounds are produced regioselectively and extremely easily. These five-membered ring products have applications in many fields, such as catalysts for a wide range of

https://doi.org/10.1007/978-3-658-32421-6a 1963 article on the reaction of an azobenzene with a nickel compound. However, the verification of the intramolecular bond was incorrectly assigned in that article as the N=N π-coordination bond to the nickel atom. For this reason, an article on the reaction of azobenzene with a Pd or Pt atom publ

Halbleiter und Fotoelektrochemiestudies have been on σ-coordination compounds, however, because the products are five-membered ring compounds that are extremely easily regioselectively synthesized by cyclometalation reactions. Since the 1970s, the author has compiled a great many articles on them and has published many reviews and

Hirnforschung und der freie Willelation reactions: The first is metal activation by the coordination of lone electron pair of a hetero atom to a metal atom. The second is the chelate effect caused by the formation of a five-membered ring. The third is also metal activation by ligands, such as hetero atom groups (e.g., bipyridines,
