Article abstract of DOI:10.1016/0022-328X(92)80028-V

Mono- and 1,1'-disubstituted metallocenes, XC5H4MC5H4Y, M = Fe, Ru, X = H, Y = COPh, or X = Y = COPh, have been reduced using the LiAlH4-Chirald complex to afford the corresponding carbinols and diols enantiomerically enriched.Optical yield was 53percent
