F. Balssa et al., REACTION OF ALPHA-HALOGENOESTER CARBANIONS WITH CATIONIC (ETA(6)-ARENE) TRICARBONYLMANGANESE COMPLEXES, Bulletin de la Societe chimique de France, 134(5), 1997, pp. 537-541
The reaction of methyl 2-lithio 2-chloro and 2-lithio 2-bromopropanoat
e with cationic (arene)tricarbonylmanganese complexes affords the corr
esponding neutral (eta(5)-cyclohexadienyl) tricarbonyl complexes. Only
one regioisomer is observed in the case of toluene and anisole comple
xes. The X-ray analysis of the complex due to the addition of methyl 2
-lithio 2-chloropropanoate to the (benzene) manganese complex is repor
ted.
