A novel one-pot synthesis of homochiral (R)-(-)- and (S)-(+)-Fe(CO) (η5-C5H5)(PPh3)COCH3
Cook SJ., Costello JF., Davies SG., Kruk HT.
Treatment of the salt [Fe(CO)2(η5-C 5H5)(PPh3)]Br with potassium L-mentholate followed by lithium bromide and methyllithium generates, after work-up and crystallisation, homochiral (S)-(+)-[Fe(CO)(η5-C 5H5)(PPh3)COCH3] in ≥ 30% yield.
