General description

P,P-Dichlorophenylphosphine (DCPP) is a key compound in organic synthesis. It is widely used to prepare flame retardants, nylon stabilizers, plasticizers, and organophosphorus compounds. It can be prepared by the Friedel-Craft reaction between phosphorus trichloride and benzene in the presence of anhydrous aluminum chloride as a catalyst.

Application

P,P-Dichlorophenylphosphine is used as a reactant to synthesize racemic [1]ferrocenophanes (mixture of cis and trans isomers)

The development of effective photosensitizers is particularly attractive for photodynamic therapy of cancer. Three novel porphyrin photosensitizers functionalized with phosphinic groups were synthesized and their physicochemical, photophysical, and photobiological properties were collected. Phosphinic acid groups (R1R2POOH) attached to the porphyrin

A series of 2-phosphino-1,3-diphosphonium trifluoromethanesulfonate salts has been prepared and comprehensively characterized. The compounds represent rare examples of salts containing triphosphorus dications and establish important structural and spectroscopic parameters and trends for catenated phosphorus chains.
