Thermal and light induced electron transfer reactions of main group metal hydrides and organometallics

摘要: In spite of their practical importance for organic synthesis and industrial catalysis, main group metal hydrides organometallic compounds without active d orbitals at the center have received relatively little attention with regard to obvious potential electron transfer reactivity. One reason this neglect lies in frequent complications arising from solvent-dependent self-association carbanion or hydride exchange equilibria. These are due polar metal-to-carbon metal-to-hydrogen bonds simultaneous presence a coordinatively unsaturated electrophilic electron-rich carbanionic hydridic substituents. On other hand, special, electronically ambivalent situation favors coordination-assisted, i.e. inner sphere acceptor substrates via potentially photoreactive charge complexes.
