1,1'-Bis(methylphenylphosphanyl)ferrocene: Synthesis and Complexes with the Tetracarbonylchromium Fragment
Herberich, Gerhard E.,Moss, Stefan
, p. 689 - 694 (2007/10/03)
1,1'-Bis(methylphenylphosphanyl)ferrocene (mppf) (2) was synthesized from dilithioferrocene and PMePh(OC6H4-4-Me).The diastereomers rac-2 and meso-2 were separated by fractional crystallization from ethanol.The tetracarbonylchromium complexes (rac-2)Cr(CO)4 (rac-5) and (meso-2)Cr(CO)4 (meso-5) were obtained photochemically from hexacarbonylchromium and mppf in near quantitative yield.The structures of rac-2, rac-5, and meso-5 were determined by X-ray crystallographic analysis. - Keywords: Ferrocene, 1,1'-bis(methylphenylphosphanyl)-; Chromium, carbonyl-, phosphane derivatives
PHOSPHORORGANISCHE VERBINDUNGEN 93 Zur Chemie optisch aktiver Phosphinigsaereamide

Optically active ethyl-phenyl-phosphinous acid diethylamide 1 was treated with HCl, HBF4, alcohols, thiols, carboxylic acids, esters, anhydrides, acid chloride, compounds with the structure element P-Cl and secondary phosphines to give in each case a racemic mixture of the corresponding, previously described, reaction products.Reaction of optically active 1 with para-cresol, para-cresyltrifluoro-acetate or 2,2,2-trifluoro-ethyl-trifluoro-acetate gives the corresponding optically active ester of ethyl phenyl phosphinous acid under retention of configuration.
