Chiral co-ordination of bridging formamido-ligands in clusters of type [HOs3(CO)10(µ-RNHCO)]
Abstract
Enantiomers of [HOs3(CO)10(µ-PhCH2NHCO)] interconvert slowly on an n.m.r. time-scale and diastereomers of [HOs3(CO)10(µ-PhCHMeNHCO)] have been separated by t.l.c. and characterised by their 1H n.m.r. and c.d. spectra.
