Synthesis and Spectroscopic Characterization of Eight Chloro Cyclopentadienyl Titanium Bis (O, O-Dialkyl and Alkylene Dithiophosphate) Compounds

Abstract

A series of new complexes, CpTiCl[S 2 P(OR) 2 ] 2 (where R) Et, n-Pr, i-Pr, Bu i , Ph) and CpTiCl [S 2 POGO] 2 (where G) -CH 2 CMe 2 CH 2 -, -CMe 2 CMe 2 -) have been prepared by the drop wise addition of the appropriate O, O'-dialkyl or -alkylene dithiophosphoric acid to cyclopentadienyl titanium trichloride in 1:2 molar ratio and refluxed in benzene solution. The new compounds were characterized by molecular weight measurements elemental analyses and spectroscopic studies ( 1 H, 13 C, and 31 P NMR, and infrared). We suggest a distorted tetrahedron structure of these new complexes and the dithioligand behaves as bidentate ligand.
