Complexes of Dichlorobis(Cyclopentadienyl)Titanium(IV) with N-(Aryl)-2-Mercaptoacetamides

Abstract

Bis(cyclopentadienyl)titanium(IV)mercaptoacetamided e r i v a t i v e s of t h e t y p e Cp2Ti(MA)C1 and Cp2TI(MA)2 (Cp = cyclopentadienyl and MAH = N-(aryl)-2-mercaptoacetamide; a r y l = phenyl, g -t o l y l , m-tolyl, p -t o l y l o r -naphthyl) have been prepared from t h e r e a c t i o n s of d i c h l o r o b i s (cyclopentadienyl) t i t a n i u m ( I V ) (Cp2TiC12) with v a r i o u s mercaptoacetamides i n t e t r a h y d r o f u r a n (THF) a t mom temperature i n t h e presence of t r i e t h y lm i n e ( E t 3 N ) . These new mercaptoacetamide d e r i v a t i v e s have been c h a r a c t e r i z e d by t h e i r elemental analyses, e l e c t r i c a l conductance, I R , 'H NMR and e l e c t r o n i c s p e c t r a l data.

Synthesis and Characterization of Organoarsenic(III) Derivatives with 2-Aminocyclopentene 1-Carbodithioc Acid and with Their Nitrogen/Sulfur Alkyl Derivatives

“…In view of the above, we were interested in synthesizing and characterizing some organo-arsenic(III) derivatives with the abovementioned ligands. Recently, arsenic-sulfur (trialkyltri) thioarsenites 5,6 and complexes of N-aryl2-mercaptoacetamides with cyclopentadienyl titanium 7 (IV ) have also been reported, which reflects interest in arsenic-sulfur ligand chemistry of metals.…”

“…In some cases, these bind with the metal through sulfur-sulfur coordination and sulfur-nitrogen coordination. 4 A survey of the literature reveals that only stray references [5][6][7][8] are available in the literature on the synthesis and characterization of organoarsenic (III) derivatives. In view of the above, we were interested in synthesizing and characterizing some organo-arsenic(III) derivatives with the abovementioned ligands.…”
