Distinguishing Fischer and Schrock compounds

Post  CrMoW on Mon Feb 06, 2012 4:18 pm

Heya,

just looking at my lecture notes from an organometallics lecture and was wondering how to distinguish compounds wrt Fischer and Schrock only by looking at the given structure.
I was given

(CO)5Cr=C(OMe)(Me) as "obviously" a Fischer type carbene and (Cp)2(Me)Ta=CH2 as a Schrock-type.

Due to the elements position in the periodic table the Fischer = late TM and Schrock= early TM theory cannot really apply here.
So, is the only thing to look out for the R groups (ie Fischer = heteroatom, Schrock =alkyl) or is there a better way to distinguish those compounds?

Thanks a lot for your help!!!
