Mossbauer Spectra

Single-crystal X-ray diffraction studies have been carried out on the tetradentate SnII complex N,N′-(4,5-dimethyl-1,2-phenylene ) bis ( salicylideneiminato )tin(II) [ Sn ( saldph )] and the tetradentate complex N-(2-oxidophenyl) salicylideneiminatotin (II) [ Sn ( salop )]. Sn ( saldph ) is a monomer and has the SnII ion 1.126(1)Ǻ above the plane of the O2N2 donors while Sn ( salop ) is dimeric with bridging between SnII ions by the oxygens of the oxidophenyl groups. SnII ions are raised above the O3N donor planes by 1.109(7)Ǻ while the molecules are bent along the bridging O-O axis with a dihedral angle between the chelate planes of 92.1°. The Mossbauer spectra of the complexes are reported. The SnII salicylideneimines react with H2O and oxygen but are inert to alkyl halides.

Treatment of racemic 1-(diphenylphosphanyl)-2-[(methoxycarbonyl)methyl]ferrocene successively with NaN(SiMe3)2 and methyl iodide affords the C-alkylated product, 1-(diphenylphosphanyl)-2-[1-(methoxycarbonyl)ethyl]ferrocene (6), as a mixture of diastereoisomers in ca. 10:1 ratio, from which the major (S,Rp/R,Sp)-diastereoisomer is easily isolated by crystallisation. (S,Rp/R,Sp)-6 reacts with [Pd(LNC)(MeCN)2]ClO4 (LNC = 2-[(dimethylamino-κN)- methyl]phenyl-κC1) to give the cationic bis-chelate complex (S,Rp/R,Sp)-[Pd(LNC)(6-κ2O,P)]- ClO4 (9). The structures of (S,Rp/R,Sp)-6 and 9 have been determined by single-crystal X-ray diffraction. Hydrolysis of ester 6 to the corresponding carboxylic acid proved to be difficult, being complicated by racemisation at the chiral carbon atom and oxidation of the phosphanyl group.
