DESCRIPTION:Main group metal catalysis is of great current interest due to 
 its potential to circumvent the high cost and toxicity of common transitio
 n metal catalysts.1 One of the major hurdles in this area is the lack of o
 xidative additions of robust s bonds (e.g. H‒X\, C‒X\, P‒P\, S‒S) to main 
 group centres.2\,3\,4 However\, recent work has demonstrated the ability o
 f low valent main group compounds to mimic transition metal complexes in t
 he cleavage of strong single bonds.2\n\nWe have recently reported facile a
 ctivation of H‒X bonds (where X = H\, B\, Al\, C\, Si\, N\, P\, O) by the 
 β-diketoiminato stabilized complex of aluminum in the +1 oxidation state\,
  1.5 We have since extended the scope of bond activations to other single 
 bonds including carbon‒oxygen\, carbon‒sulfide\, and carbon‒halide as well
  as element‒element bonds in disulfides and diphosphines.6 Complex 1 is ab
 le to oxidatively add the very robust C-F bonds in aryl and alkyl fluoride
 s.7 We are now very well positioned to cleave multiple bonds X=Y (X=C\, P\
 ; Y=S\, N\, O).8\n\nOur efforts to prepare zero-valent main-group complexe
 s will be also discussed.9\n\n1. P. P. Power\, Nature 2010\, 463\, 171-177
