- A convenient synthesis of tertiary phosphines from red phosphorus and aryl-or heteroarylethenes
-
Tertiary phosphines (RCH2CH2)3P (R = aryl, heteroaryl) have been obtained in good yields by nucleophilic addition of potassium phosphide, generated from red phosphorus, potassium and t-butanol in liquid ammonia, to aryl-an

- Photochemical transformation of chlorobenzenes and white phosphorus into arylphosphines and phosphonium salts
-
Chlorobenzenes are important starting materials for the preparation of commercially valuable triarylphosphines and tetraarylphosphonium salts, but their use for the direct arylation of elemental phosphorus has been elusive. Here we describe a simple photochemical route toward such products. UV-LED irradiation (365 nm) of chlorobenzenes, white phosphorus (P4) and the organic superphotoreductant tetrakis(dimethylamino)ethylene (TDAE) affords the desired arylphosphorus compounds in a single reaction step.

- Method for compounding organphosphorus by using black phosphorus
-
The invention discloses a method for compounding organphosphorus by using black phosphorus. The method takes the black phosphorus as a reaction raw material, safely and efficiently compounds organic phosphate, sulpho-phosphite ester, amino phosphite ester, alkylphosphine, alkylphosphine oxide and other organphosphorus with wide usages, a conventional synthsis route by using phosphorus halide and phosphate to compound the organphosphorus is avoided, the synthesis steps are simple and short, the production technology is operated simply and easily, the reproducibility is good, the reaction is simple and green, the use of a phosphorus halide reagent is avoided, the range of the synthetic organphosphorus is wider, the method satisfies the requirements of green chemical development, and the large-scale production can be achieved.

- One-pot microwave synthesis of tertiary phosphine sulfides directly from aromatic alkenes, elemental phosphorus and sulfur in KOH-DMSO system
-
Aromatic alkenes (vinylbenzene, 1-(tert-butyl)-4-vinylbenzene, 1-chloro-4-vinylbenzene) react with red phosphorus and elemental sulfur in the superbasic system KOH-DMSO(H2O) under microwave irradiation (600 W, 6-8 min, Ar) in the presence of hydroquinone to afford tris(2-phenylethyl)-, tris[2-(4- tBu-phenyl)ethyl]- and tris[2-(4-Cl-phenyl)ethyl]phosphine sulfides in 53%, 38% and 42% yield, respectively.
