“…Thin layer chromatography (TLC) was performed on silica gel 60 F254-coated aluminum foils (Fluka). Benzothiadiphosphole was prepared as reported in the literature [2][3][4][5][6][7][8][9]. Cardanol derivatives were purchase from Sigma-Aldrich.…”

“…In the past, we reported [4] that benzothiadiphosphole (1) can be easily obtained via a reaction between p-methylthioanisole, PCl 3 and AlCl 3 , and it can be used as efficient phosphorus-donating reagent to obtain a plethora of phosphine derivatives [5][6][7][8]. Subsequently, we found that 1 can be easily transformed in similar structures bearing P-As, P-Sb, or P-Bi bonds that are able to produce arsines, stibines, or bismuthines [9].…”

2,9-Dimethyl-11-(3-pentadecylphenoxy)dibenzo[c,f][1,2,5]dithiaphosphepine 11-oxide was synthesized (yield 50%) by a two-step procedure. The first step starts with a benzothiadiphosphole and bis-Grignard reagent, and the second step consists of adding the sodium salt of a derivative of cardanol. The structure of newly synthesized compound was elucidated based on 1H-NMR, 13C-NMR, 31P-NMR, IR, Electron Spray Ionization (ESI)–MS, Gas Chromatography-Mass Spectroscopy (GC–MS), and Electron Spray Ionization-High Resolution Mass Spectroscopy (ESI–HRMS).
