【Abstract】 Pentachloro 12 H dibenzodioxaphosphocin 6 sulfide(5) was prepared in high yield from bis(2 hydroxy 3,5 dichlorophenyl)methane(4) and PSCl 3. When 5 was reacted with phenols in the presence of anhydrous K 2CO 3 and Cu powder. Tetrachloro 6 aryloxy 12 H dibenzodioxaphosphocin 6 sulfides(6) were obtained, Treatment of 5 with RONa ROH solution led to compounds 7, 6 alkoxyl analogues of 6. In the presence of Et 3N, 5 reacted with propanol offered tetrachloro 6 hydroxy 12 H dibenzodioxaphosphocin 6 sulfide triethylamine salt(8). When 8 was refluxed in DMSO, the corresponding phosphocin 6 oxide 9 was obtained.更多还原
