The tremendous progress in olefin metathesis achieved during the last decade can hardly be overestimated. Due to the development of a new generation of well defined and high-performance organometallic catalysts, this reaction is rapidly evolving into one of the most versatile tools for advanced organic chemistry, natural product synthesis, fine chemical production and polymer sciences. Written by...
Tremendous advances in the field of alkyne metathesis have been recorded over the last decade. The development of molybdenum alkylidyne complexes endowed with silanolate ligands allowed several problems of traditional alkyne metathesis to be solved at once. As occurs in the molybdenum series, alternation of the ancillary ligands about the high‐valent tungsten center imparts significant changes in...
This chapter illustrates the scope and limitations of alkyne metathesis, which has become a powerful tool of contemporary organic synthesis. It begins with a discussion on classical catalyst systems and state‐of‐the‐art catalysts. The generally accepted mechanism of alkyne metathesis, originally proposed by Katz and McGinnis, follows the logic of the Chauvin cycle of olefin metathesis. It consists...
