REACTIONS OF GROUP VIB HEXACARBONYLS WITH FORMAMIDINES.
De Roode,Vrieze
, p. 209 - 220 (1977)
The reaction of molybdenum and chromium hexacarbonyls with formamidines yields the tetrakis(formamidinato)dimolybdenum and dichromium complexes. In the case of molybdenum, a reaction scheme has been set up for the formation of these complexes. An interesting feature of the chemistry of these complexes is the reaction with Mo(CO)//6 or Cr(CO)//6 to yield novel complexes in which an ″M(CO)//3″ species is bound to one of the aromatic groups. Their physical and chemical properties are discussed. The reaction of W(CO)//6 with formamidine did not produce a complex analogous to that obtained with Mo(CO)//6 or Cr(CO)//6 but, instead, a deep purple colored complex.
