Abstract

Phenylarsenic(III) and Phenylantimony(III) Bis(dialkyl dithiophosphates): Synthesis and Multinuclear ( , 13C, 31P) NMR and Mass Spectral Studies. Crystal and Molecular Structures of QH5M[S2P(0-/-Pr)2]2 [M = Sb(III) and As(III)]

The antispermatogenic activity of some phenylbismuth(III) O,O′‐dialkyldithiophosphates

“…However, only one set of signals was observed for alkyl group protons (in 1 H NMR spectra) and alkyl group carbons (in 13 C NMR spectra), which indicates that the intramolecular interaction between phenyl group and alkyl groups (which are above the basal plane) is not significant, probably due to the larger size of bismuth. Similar results were observed in the case of PhSb[S(S)P(OR) 2 ] 2 compounds, 28 in which all alkyl groups are equivalent. However, in analogous arsenic compounds, 28 PhAs[S(S)P(OR) 2 ] 2 , the splitting in the NMR signals of these alkyl groups (both in 1 H and 13 C) was observed.…”

Since the size of Bi is larger than As and even with Sb, it is not surprising that the splitting of signals does not take place in the present case.…”

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

“…The singlet peak at (3.1 -3.5 ppm) in the parent ligand assigned to SH proton, is absent from the spectra of chloro cyclopentadienyl titanium bis (dialkyl and alkylenedithiophosphate) derivatives indicating deprotonation of SH group and forming of Ti-S bond [30].…”

Convenient Route to Alkylene Dithiophosphato Ligands: Synthesis and Crystallographic Analysis of [OCH2CMe2CH2OPS2HNEt3]

“…Subsequently, cyclic analogous alkylene dithiophosphoric acids, OGOPS 2 H, (where G = 1,2-and 1,3-glycols) were reported by Bhasin et al [15]. Later, several papers have been published on metal/metalloid derivatives of alkylene dithiophosphates [16][17][18][19][20][21][22][23][24] depicting the versatile nature of these ligands. In general, universal bi-dentate nature of these ligands have been established [25][26][27][28] with few exceptions in compounds with triorganotin(IV) moieties, where these behaved in less common monodentate linkages [29,30].…”
