The asymmetric transfer hydrogenation (ATH) of ferrocenyl ketones, such as FcC(O)CH 2 Y [Fc = ferrocenyl, Y = H ( 1a ), CH 3 ( 1b ), Cl ( 1c ) or N 3 ( 1d )] has been carried out using the Noyori/Ikariya catalysts [(−)-(1 R ,2 S )-ephedrine] or N -

Racemic planar chiral (η 6 -aryl ketone)Cr(CO) 3 complexes (aryl ketone = 1-indanone, 1-tetralone, 4-chromanone and thiochroman-4-one) were prepared by refluxing the aryl ketone with Cr(CO) 6 in a 10:1 mixture of dibutyl ether and THF. The reduction

A synthetic study was carried out to obtain epimers of a protected 2,4-dihydroxy-3-methylpentanoic ester 9, which is a central building block of the immunomodulator (+)-conagenin 1. The configuration of the three contiguous stereogenic centers was de

The trinuclear platinum cluster Pt3(m-CNBut)3(CNBut)3 reacts selectively with the monodentate dppm-iron complex Fe(dppm-P)(CO)4 (1:1 or 2:1 ratios of Pt:Fe) dppm = bis(diphenylphosphino)methane, to give the mixed-metal cluster FePt2(m-dppm)(CNBut)2(C
