Triphenylphosphine (IUPAC name: triphenylphosphane) is a common organophosphorus compound with the formula P(C 6 H 5) 3 and often abbreviated to P Ph 3 or Ph 3 P. It is versatile compound that is widely used as a reagent in organic synthesis and as a ligand for transition metal complexes, including ones that serve as catalysts in organometallic ...
Specific treatments for acute pesticide poisoning are often dependent on the pesticide or class of pesticide responsible for the poisoning. However, there are basic management techniques that are applicable to most acute poisonings, including skin decontamination, airway protection, gastrointestinal decontamination, and seizure treatment.

Triphenylphosphine oxide (often abbreviated TPPO) is the organophosphorus compound with the formula OP(C 6 H 5) 3, also written as Ph 3 PO or PPh 3 O (Ph = C 6 H 5). It is one of the more common phosphine oxides. This colourless crystalline compound is a common but potentially useful waste product in reactions involving triphenylphosphine.
Toxic encephalopathy is a neurologic disorder caused by exposure to neurotoxic organic solvents such as toluene, following exposure to heavy metals such as manganese, as a side effect of melarsoprol treatment for African trypanosomiasis, adverse effects to prescription drugs, or exposure to extreme concentrations of any natural toxin such as cyanotoxins found in shellfish or freshwater ...
Phosphine (IUPAC name: phosphane) is a colorless, flammable, highly toxic compound with the chemical formula P H 3, classed as a pnictogen hydride.Pure phosphine is odorless, but technical grade samples have a highly unpleasant odor like rotting fish, due to the presence of substituted phosphine and diphosphane (P 2 H 4).
The array of symptoms typically seen in carbamate poisoning include both muscarinic and nicotinic symptoms. [1] Muscarinic receptor effects include: Bradycardia, or reduced heart rate; Bronchospasm, or tightening of the bronchioles of the lungs; Miosis, or constriction of the pupils; Vomiting and abdominal pain; Diarrhea; Excessive sweating and ...
Symptoms vary widely between sources of toxicity, dosage, length of time patient was exposed to the toxic substance, patient history, and patient genetics. Especially in the case of leukoencephalopathy developing due to substance use or environmental toxins, symptoms typically do not develop until several days to months after exposure to the ...
Treatment of this species with hydroxylamine in the presence of Ph 3 P results in replacement of the two single P–Cl bonds in Ph 3 PCl 2 by one double P=N bond: 2 Ph 3 PCl 2 + NH 2 OH·HCl + Ph 3 P → [(Ph 3 P) 2 N]Cl + 4HCl + Ph 3 PO. Triphenylphosphine oxide Ph 3 PO is a by-product. Bis(triphenylphosphine)iminium chloride is described as ...
