Fausto Calderazzo (March 8, 1930, Parma – June 1, 2014, Pisa) was an Italian inorganic chemist. He is known for his pioneering work in organometallic chemistry, particularly in carbonyl chemistry.[1] His research spanned from synthesis to mechanistic studies, notably proving the mechanism of migratory insertion with colleague Klaus Noack.[2]

Biography

Fausto Calderazzo was born in Parma, Italy, on March 8, 1930. He pursued chemistry at the University of Florence, graduating with a research project on nickel hydrazide complexes.[3] His career included significant contributions at the Polytechnic University of Milan and the University of Pisa, where he led research in organometallic chemistry and taught advanced courses.

Early Life and Higher Education

Calderazzo's higher education began at the University of Florence, where he completed his degree in 1952. His early research was influenced by Luigi Sacconi, who guided him towards inorganic chemistry.[4]

Career

After military service, Calderazzo joined Giulio Natta's group at the Polytechnic University of Milan, focusing on organometallic chemistry and carbonyl derivatives.[5] In 1959, he collaborated on the discovery of vanadium hexacarbonyl, a significant paramagnetic metal carbonyl.[6]

In 1960, he became a Sloan Fellow at MIT, working with F. Albert Cotton.[8] From 1963 to 1968, he directed the Inorganic Synthesis Group at the Cyanamid European Research Institute in Geneva, where he conducted groundbreaking work on migratory insertion.[9]

In 1968, Calderazzo returned to Italy as a Full Professor at the University of Pisa, where he continued his research and teaching, funded by various industries. His work in Pisa included studies on late transition metals and carbonyl chemistry.[10]

Awards and Titles

Calderazzo received the A. Miolati award in 1988 and the L. Sacconi Medal in 1998. He was a member of various international scientific journals and societies, including the Accademia Nazionale dei Lincei.
