The reactions of M≡C and C≡C bonds tend to afford cycloaddition intermediates or products on account of their high degree of unsaturation. For example, the alkyne metathesis undergoes metallacyclobutadiene intermediates process12,13,14, and [2+2], [2+2+1], and [2+2+2] cycloaddition pro...

For example, reactions with the halogens bromine or iodine give the oxidative addition products 168a,b (Scheme 3.49). Also, the iridium center in 62 can be oxidized simply through treatment with silver tetrafluoroborate to give the dicationic iridabenzene 169 (Scheme 3.49).61 An analogous ...
There are two main types of addition reactions: nucleophilic addition and electrophilic addition. When the pi bond is between two carbon atoms (such as with an alkene or alkyne), then the reaction is an electrophilic addition reaction. This is because the compound that is added to the pi ...
Monomers, initiators with a transferable atom (generally a halogen), and catalysts (transition metals with suitable ligands) are the main constituents of ATRP. In some cases an additive (metal salt in a higher oxidation state) may be used. Solvents used and temperatures applied are important par...
