Mf. Semmelhack et al., Preparation and structure of chiral carbene complexes of manganese and iron from terminal alkynes, ORGANOMETAL, 20(19), 2001, pp. 4114-4117
Chiral-at-the-metal Fischer carbene complexes are prepared by reaction of c
oordinatively unsaturated Cp(NO)(Ph3P)Mn(+) or Cp(CO)(Ph3P)Fe(+) by intramo
lecular rearrangement of hydroxyalkynes and the parallel reaction of methyl
alcohol with TMS-acetylene.
