Efficient synthesis of fatty monoglyceride sulfates from fatty acids and fatty acid methyl esters
Autor: Fahim U. Ahmed
Publikováno v: Journal of the American Oil Chemists' Society. 67:8-14
An efficient high yield synthesis of fatty monoglyceride sulfates from fatty acids or fatty acid methyl esters, glycerine and chlorosulfuric acid in chloroform using stoichiometric amounts of reagents was developed. Sodium coco monoglyceride sulfate

Synthesis of allyl-transition metal complexes by phase transfer catalyzed reactions of metal carbonyl halides
Autor: Dorothy H. Gibson, Wen-Liang Hsu, Fahim U. Ahmed
Publikováno v: Journal of Organometallic Chemistry. 215:379-401
Mechanisms are proposed for the hydroxide ion-initiated reactions of metal carbonyl halides which lead to allyl-transition metal complexes under phase transfer conditions. Evidence is presented for intermediate anionic metallocarboxylic acids in reac

Phase transfer catalyzed reductions of metal carbonyls
Autor: Kenneth R. Phillips, Fahim U. Ahmed, Dorothy H. Gibson
Publikováno v: Journal of Organometallic Chemistry. 206:C17-C20
Reductions of metal carbonyl halides and some metal carbonyls by quaternary ammonium borohydrides in phase transfer catalyzed reactions are described. The method provides an efficient synthetic route to metal carbonyl anions from BrMn(CO) 5 , C 5 H 5

Generation of group VI binuclear metal carbonyl dianions by ion-pair extraction
Autor: Kenneth R. Phillips, Dorothy H. Gibson, Fahim U. Ahmed
Publikováno v: Journal of Organometallic Chemistry. 276:363-366
Ion-pair extraction has been used to provide a new synthetic route to binuclear dianions of the type M2CO)102− (M = Cr, Mo, W) from the corresponding μ-hydrido anions; yields are good to excellent (62–90%). 13C NMR data for the binuclear dianion

Hypolipidemic Activity of Trimethylamine-Carbomethoxyborane and Related Derivatives in Rodents
Autor: Fahim U. Ahmed, Samir Jafri, Bernard F. Spielvogel, Anup Sood, Iris H. Hall
Publikováno v: Journal of Pharmaceutical Sciences. 76:359-365
A number of substituted amine-carboxyborane esters were examined for their hypolipidemic activity in rodents. Trimethylamine-carbomethoxyborane, Me3NBH2C(O)OMe, was observed to be the most effective hypolipidemic agent in the rodent at the low dose o

Reductions of metal carbonyls by quaternary ammonium borohydrides
Autor: Fahim U. Ahmed, Kenneth R. Phillips, Dorothy H. Gibson
Publikováno v: Journal of Organometallic Chemistry. 218:325-336
Quaternary ammonium borohydrides, used directly or generated in phase transfer reactions, are highly effective reagents for preparing metal carbonyl anions from metal carbonyls [Mo(CO) 6 , Mn 2 (CO) 10 , Re 2 (CO) 10 , CO 2 (CO) 8 , Fe 3 (CO) 12 , Ru
