Usage

General Description

Diphenyl anilinophosphonate is a chemical compound with the formula C12H11NO2P. It is a phosphonate ester, which means it contains a phosphorus atom that is bonded to two oxygen atoms and to a carbon atom of an aniline group. Diphenyl anilinophosphonate is commonly used as a flame retardant and plasticizer in various materials such as plastics, polymers, and resins. Its ability to reduce the flammability of these materials makes it a valuable additive in the manufacturing of items such as electrical equipment, cables, and textiles. Diphenyl anilinophosphonate is also known for its thermal stability and resistance to leaching, making it a reliable choice for long-term fire protection. Additionally, its low toxicity and relatively low cost make it a preferred option for many industrial applications.

Kinetics and mechanism of the anilinolysis of aryl phenyl isothiocyanophosphates in acetonitrile

Kinetic studies on the reactions of Y-aryl phenyl isothiocyanophosphates with substituted X-anilines and deuterated X-anilines were carried out in acetonitrile at 55.0 °C. The free-energy relationships with X in the nucleophiles were biphasic concave upwards with a break region between X = H and 4-Cl, giving unusual positive ρX and negative βX values with less basic anilines (X = 4-Cl and 3-Cl). A stepwise mechanism with rate-limiting bond breaking for more basic anilines and with rate-limiting bond formation for less basic anilines is proposed based on the positive and negative ρXY values, respectively. The deuterium kinetic isotope effects involving deuterated anilines (XC6H4ND2) showed primary normal and secondary inverse DKIEs for more basic and less basic anilines, rationalized by frontside attack involving hydrogen-bonded four-center-type TSf and backside attack TSb, respectively. The positive ρX values with less basic anilines are substantiated by the tight TS, in which the extent of the bond formation is great and the degree of the bond breaking is considerably small.
