Stereoselective methylation of co-ordinated phenylphosphine: crystal and molecular structure of [(R*,R*),(R*)]-[(η5-C5H5){{1,2-C6H4(PMePh)2}FePHMePh]PF6·0.5CH2Cl2
Abstract
Reaction of (R*,R*)-[(η5-C5H5){{1,2-C6H4(PMePh)2}FePHMePh]PF6 with iodomethane in the presence of triethylamine at 20 °C produces a separable 4 : 1 mixture of [(R*,R*),(R*)]- and [(R*,R*),(S*)]-[(η5-C5H5){{1,2-C6H4(PMePh)2}FePHMePh]PF6η the crystal and molecular structure of the major [(R*,R*),(R*)] diastereoisomer is reported.
