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 chemistry.
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.
The major lethal consequence of aluminium phosphide ingestion is profound circulatory collapse, and is reportedly secondary to these toxins generated, which lead due to direct effects on cardiomyocytes, [3] fluid loss, and adrenal gland damage. [4] The signs and symptoms are non-specific, dose dependent and evolve with time passing.
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).
Triphenyl phosphate exhibits low acute toxicity by dermal or oral contact. [3] However, an increasing number of studies have linked exposure to TPhP with reproductive and developmental toxicity, neurotoxicity, metabolic disruption, endocrine effects, and genotoxicity. [6] [8] [9] TPhP has also been found to induce significant estrogenic activity.
If a drug can bind to unexpected proteins, receptors, or enzymes that can alter different pathways other than those desired for treatment, severe downstream effects can develop. An example of this is the drug eplerenone (aldosterone receptor antagonist), which should increase aldosterone levels, but has shown to produce atrophy of the prostate.
The debate over whether people ages 60 and up should take aspirin continues as medical experts learn more about the potential pros and cons of long-term use.. Aspirin is an over-the-counter ...
Tetrakis(triphenylphosphine)palladium(0) is widely used to catalyse C-C coupling reactions in organic synthesis, see Heck reaction. Wilkinson's catalyst , RhCl(PPh 3 ) 3 is a square planar Rh(I) complex of historical significance used to catalyze the hydrogenation of alkenes.
