Usage

General Description

Tetramethyl thioperoxydiphosphate, also known as TTP, is a chemical compound that is commonly used as a reagent in organic synthesis. It is a highly reactive compound that is known for its ability to transfer oxygen atoms to other molecules, making it useful in a variety of oxidation reactions. TTP is also used in the production of pesticides and insecticides due to its ability to disrupt the metabolism of insects. However, TTP is also toxic and poses a risk to human health, as exposure to this compound can cause skin and eye irritation, respiratory issues, and potential long-term health effects. Therefore, proper handling and safety precautions are necessary when working with tetramethyl thioperoxydiphosphate.

13C and 31P Solid-State NMR Studies of Bis(dialkoxythiophosphoryl) Disulfides

The principal elements of the chemical shift tensors for the phosphorus atoms in three bis(dialkoxythiophosphoryl) disulfides were determined from both static and magic angle spinning NMR spectra, using the intensities of the peak in the spinning sidebands relative to those of the central band in the latter method.These studies show that it is possible to deduce a mode of molecular motion in the solid state by analysis of the shielding parameters.Variable-temperature 13C and 31P CP MAS NMR of these samples from 190 to 320 K revealed a peculiar motion of the methoxy group and a rigid P-S-S-P backbone for bis(dimethoxythiophosphoryl) disulf ide.In addition, these studies confirmed that it is possible to distinguish the different x-ray crystal structures from the solid-state NMR experiments.

REDOX REACTIONS OF ANTIMONY(III) O,O-DISUBSTITUTED PHOSPHORODITHIOATES WITH FERRIC CHLORIDE

The reaction of antimony(III) tris-(O,O-diethylphosphorodithioate) with three equivalents of ferric chloride in ether solution has been found to give ferrous chloride, bis-(O,O-diethylthiophosphoryl) disulfide and dichloroantimony O,O-diethyl phosphorodithioate as the major products.However, a relatively low yield of bis-(O,O-diethylthiophosphoryl) trisulfide was also obtained.The structures of these products were established by independent syntheses.Several additional antimony(III) tris-(O,O-disubstituted phosphorodithioates) were prepared, and the major organic product obtained by reaction of each of these compounds with three equiva lents of ferric chloride was the corresponding bis-(O,O-disubstituted thiophosphoryl) disulfide.A mechanism for this reaction has been suggested, and evidence in support of the mechanism has been presented.The various antimony(III) tris-(O,O-dialkyl phosphorodithioates) are passivating agents in petroleum refining.The results reported in this and in our previous papers indicate that such compounds undergo a variety of reactions with components of crude petroleum prior to the ultimate pyrolysis reactions which occur in the fluid catalytic cracking process.
