... 2.2. Development of a Photochemical Catalytic Functionalization of Alkanes These results implied that boryl complexes could be used as intermediates in a catalytic functionalization of alkanes and arenes. However, a catalytic cycle involving the Cp*M(CO)n-boryl complexes was difficult to imagine bec ...

M(CH2C6H5)4, and M[CH2C(CH3)3]4 (M = Ti, Zr, or Hf; Fig 2), were rationalized on the basis of the fact that unlike a compound having an ethyl ligand, the alkyl ligands in these species lack  hydrogens and so of course cannot undergo decomposition processes that involve  hydrogens.7 In 1973 Wilkins ...
