Organophosphate esters (OPEs) are common additives in a wide range of commercial and industrial products. Elevated prolonged exposure to OPEs may induce several adverse effects. This is concerning as they ubiquitous air, indoor dust, drinking water, other environmental matrices. However, information on the presence foodstuffs consequent health risks remains scant. review critically evaluates av...

Ionic liquids such as 1,3-dialkylimidazolium salts make excellent catalysts and solvents for synthesis of dialkyl 2-(dialkoxyphosphoryl)-3-(1-oxo-1-H-phthalazin-2-yl)succinates from 2H-phthalazin-1-one, dialkyl acetylenedicarboxylates, and trialkyl phosphites. Under similar conditions, triphenyl phosphite led to dialkyl 2-(diphenoxyphosphoryl)-3-(1-oxo-1-H-phthalazin-2-yl)succinates. The ionic ...

Anthropogenic toxic vapour and gases are a worldwide threat for human health to the environment. Therefore, it is crucial develop highly sensitive devices that guarantee their rapid detection. Here, we prepared redox-switchable colloids by in-situ reduction of 2,3,5-triphenyl-2H-tetrazolium (TTC) into triphenyl formazan (TF) stabilised with Pluronic F127 in aqueous media. The were readily embed...

BACKGROUND Organophosphate (OP) compounds, such as tris(1,3-dichloro-2-propyl) phosphate (TDCPP) and triphenyl phosphate (TPP), are commonly used as additive flame retardants and plasticizers in a wide range of materials. Although widespread human exposure to OP flame retardants is likely, there is a lack of human and animal data on potential health effects. OBJECTIVE We explored relationship...

The title compound, C(30)H(27)O(8)P (2), was formed as one of two products {(1) [Krawczyk et al. (2010 ▶). Acta Cryst. E66 (cv2752)] and (2)} in the reaction of dimethyl acetyl-enedicarboxyl-ate with triphenyl-phosphine. The mol-ecule of (2) consists of a five-membered carbocyclic ring. The P atom is a part of a triphenylphosphoranylidene substituent. In contrast to (1), the five-membered ring ...

Reaction of [Ru(Tp)Cl(PPh(3))(2)] (Tp = hydridotrispyrazolyl-borate) with ammonium dithio-benzoate in methanol leads to the formation of the title compound, [Ru(C(9)H(10)BN(6))(C(7)H(5)S(2))(C(18)H(15)P)]. In the crystal structure, the Ru atom is coordinated by three N atoms of the Tp ligand, one P atom of the triphenyl-phosphine ligand and the two S atoms of the dithio-benzoate ligand within a...

The toluene solution structure of an N-lithio(triphenyl)phosphazene (Ph(3)PNLi) mixed aggregate with lithium bromide (LiBr), 5, has been elucidated for the first time based on multinuclear magnetic resonance measurements ((1)H, (6)Li, (7)Li, (13)C and (31)P). The structure consist of two dimers [Li(mu-Z)](2) (Z= Br, NPR(3)) linked through LiX (X= N, Br) bridges. This arrangement is a cubane-lik...
