Insertion Reactions of Compounds of Metals and Metalloids Involving Unsaturated Substrates

摘要: Publisher Summary This chapter focuses on insertion reactions of compounds metals and metalloids involving unsaturated substrates. The importance lies in that their use provides elegant facile syntheses for a wide variety organometallic compounds, especially those having functional groups. majority the may be regarded as 1,2-dipolar additions. Migratory aptitude orders are likely to characteristic each element. Insertion facilitated when weak bonds broken stronger made. products were not isolated, but formation inferred from nature hydrolysates. It is relevant derivatives alkaline earth reactive 1,l-diphenylethylene can responsive nucleophilic attack. high acceptor strength requirement borane less critical alkynes, which, unlike alkenes, more typically organic often favor attack by nucleophiles. In general, metal complexes with isocyanates, isothiocyanates, carbodiimides, ketene effected at relatively low temperature without catalyst.
