Application
Dichlorotriphenylphosphorane, also known as Triphenylphosphine dichloride (PPh3Cl2), serves an essential role in various synthetic applications, owing to its properties as a phosphorus halide. It is used in the synthesis of several compounds, including tertiary benzanilide derivatives, N-phosphodipeptides, and dialkyl phosphorochloridites through the reaction with trialkyl phosphites. Additionally, it facilitates the formation of naphthalene ring-based calix[3]amide when reacted with 6-amino-2-naphthoic acid and contributes to the creation of C2v-symmetrical cyclic tetramers of aromatic amides. Its stability and reactivity, extensively analyzed by solid-state 31P NMR spectroscopy, have also made it valuable in the transformation of carboxylic esters to acid halides, where the reaction mechanism has been well-documented. Furthermore, a modified synthesis method utilizing dichlorotriphenylphosphorane has been proposed to effectively produce tertiary amides, highlighting its versatility in chemical processes.
