Starting from (R)-Ugi's amine, diastereoselective lithiation followed by Ar'PCl 2 and then Ar’’MgBr led to the generation, as single diastereoisomers, of (R,S p,S phos) [Ar’=Ph, Ar’’=o-Tol] and (R,S p,R phos) [Ar’=o-Tol, Ar’’=Ph] PPFA

All four possible diastereoisomers of phosphinofer- rocenyloxazoline (Phosferrox type) ligands containing three elements of chirality were synthesized as single enantiomers. The S-c configured oxazoline moiety (R = Me, i-Pr) was used to control the g

The palladium catalysed reaction of 1-iodo-2-methylnaphthalene and 2-methyl-1-naphthylmagnesium bromide gave quantitatively an ( S a )-configured cross-coupled product in 80% e.e. using ( R , S p )-PPFA as a ligand. N , N -Dimethylaminomethylferrocen

Chiral non-racemic palladacycles were employed as precatalysts for Pd(0) mediated asymmetric synthesis. Addition of HPAr2/base to a ferrocenyloxazoline planar chiral palladacycle resulted in ligand synthesis and palladium capture to give a bidentate

The Friedel–Crafts acetylation of pentaphenylferrocene has been revisited using 1.1 equivalents of AcCl/AlCl3 in CH2Cl2 at room temperature leading to the synthesis of 1‐acetyl‐1′,2′,3′,4′,5′‐pentaphenylferrocene (78 % yield). Incre

Starting from (S,S)-1,1′-bis(4-isopropyloxazolin-2-yl)ferrocene, all possible 2-trimethylsilyl- and 2,2′-di(trimethylsilyl)-substituted diastereoisomers, potential bisoxazoline ligands for use in asymmetric catalysis, were synthesised by selectiv
Reinvestigation of the palladation of (S)-2-ferrocenyl-4-(methylethyl)oxazoline with Pd(OAc)2 in CH2Cl2 was found to proceed with a dr of 3.6:1 in favor of the resulting S,Sp palladacycle. A similar 4:1 dr was obtained using Na2PdCl4 in MeOH. As an a

Diastereoselective lithiation of (S)-2-ferrocenyl-4-(1-methylethyl)oxazoline, followed by addition of HgCl2, resulted in the formation by transmetalation of an (S,Sp)-configured mercury substituted complex. Addition to this of [Cp*IrCl2]2 and tetrabu

Ferrocenyl (Fc) and phenyl (Ph) containing imines FcCH=NCH(R)Ph and FcCH(R)N=CHPh (R = H and Me) were cycloiridated using [Cp*IrCl2]2 with NaOAc in CH2Cl2. All resulted in the formation of neutral chloride ligated half-sandwich iridacycles as a resul

Reaction of (η5-(S)-2-(4-methylethyl)oxazolinylcyclopentadienyl)(η4-tetraphenylcyclobutadiene)cobalt with [IrCp*Cl2]2 in acetonitrile with KPF6 and KOt-Bu resulted in S,Sp,SIr and S,Rp,RIr configured acetonitrile and Cp* coordinated cationic iridac
