Mingos D. Michael P. Comprehensive Organometallic Chemistry III - From Fundamentals to Applications in 13v. Vol. 05 - Compounds of Groups 5 to 7 2007 [pdf 980sc 960c. 19.69mb] This volume reviews the preparation, properties, reactions and special applications of group 5 to 7 organometallic compounds. Each chapter examines the compounds formed between Vanadium, Niobium, Tantalum, Chromium, Molybdenum, Tungsten, Manganese, Technetium and Rhenium and specific ligands. It provides a clear and comprehensive overview of developments since 1993 and attempts to predict trends in the field over the next ten years. Like its predecessors, COMC (1982) and COMC-II (1995), this new work is the essential reference text for any chemist or technologist who needs to use or apply organometallic compounds.* valuable
