Steven Dale Ittel (born 1946 in Hamilton, Ohio) is an American chemist specializing in organometallic chemistry and homogeneous catalysis. His father was a superintendent of a rural school district and a YMCA camp director, so he spent the first 19 summers of his life at Camp Campbell Gard. He is married with two children.
He attended Miami University in Oxford, Ohio, where he received a Bachelor's degree in chemistry in 1968. He was then commissioned as an officer in the United States Public Health Service and studyed photochemical smog in the New York City metropolitan area from 1968-1970. He attended Northwestern University where he received his PhD in chemistry under the direction of James A. Ibers in 1974.
Ittel worked on hydride activation of lanthanides for Systems for Nuclear Auxiliary Power (SNAP) at Monsanto's Mound Laboratories for a short time. Upon receiving his PhD from Northwestern, Ittel joined DuPont’s Central Research Department at the Experimental Station in Wilmington, Delaware. Ittel is best known for his contributions to organometallic chemistry and homogeneous catalysis. He discovered fluxional processes in both diamagnetic and paramagnetic π-allyl organometallic complexes bearing M-H-C agostic interactions. He was responsible for a series of C-H activation reactions based upon fleeting zero-valent iron complexes bearing bidentate phosphorus ligands.
Ittel (also known as Ittel Kill or Ittel-Kyll) is a populated place in the Bitburg-Prüm district of the Rhineland-Palatinate state in Germany.
