MONOORGANOTIN(IV)O,O-ALKYLENEDITHIOPHOSPHATES

Synthesis Properties and Characterization of Di Cyclopentadienyl Vanadium Bis Dialkyl and Alkylene Dithiophosphate Complexes

“…Our observations based on spectral studies, such as IR, NMR ( 1 H, 13 C, and 31 P), magnetic susceptibility studies, molecular weight determinations, and UV spectrophotometer indicate the bidentate behavior of ligand and monomeric nature of these complexes. According to this, an trans-octahedral geometry's ( Figures 1 and 2) can be suggested for vanadium (IV) dialkyl and alkylene dithiophosphate complexes because in IR spectra one stretching have been obtain in the range 850-756, but cis-octahedral have two stretching vibrations.…”

Synthesis and spectroscopic characterization of dimethyl/di(n‐butyl)tin(IV)bis(O,O′‐ditolyl dithiophosphate) complexes. Crystal structures of Me2Sn[S2P(OC6H4Me‐o)2]2 and n‐Bu2Sn[S2P(OC6H4Me‐o)2]2

“…IR spectra were recorded on a Perkin-Elmer 577 spectrophotometer in KBr pellets in the range (4000-400) cm −1 . 1 H, 13 C NMR and 31 P NMR spectra were recorded on a Bruker DRX-300 spectrometer in CDCl 3 using TMS as an internal standard and H 3 PO 4 as an external standard, respectively.…”

Chiral S‐stannyl dithiophosphates and dithiophosphonates on the basis of monoterpenols

“…There is a considerable interest in tin(IV) derivatives of phosphorus dithioacids containing the S=P‐S‐Sn structural fragment due to their biological activity. S‐Triorganyltin dithiophosphate esters are used as bactericides, insecticides, fingicides, etc .…”

“…The review summarizes reported coordination compounds utilizing dithiophosphonates on the basis of 1,3,2,4‐dithiadiphosphetane‐2,4‐disulfides . The common methods of synthesizing S ‐organotindithiophosphates, dithiophosphinates and tetrathiophosphates were usually based on the reactions of the corresponding phosphorus dithioacids or their salts with organotin halides (also in the presence of β ‐diketones), oxides, hydroxides, tetraalkyltin or tributyltin isocyanates . We have recently developed alternative methods of synthesizing tin(IV) derivatives of phosphorus dithioacids by use tetraphosphorus decasulfide and 1,3,2,4‐dithiadiphosphetane‐2,4‐disulfides as dithiophosphorylating agents.…”
