method

Reactions of 2,4-bis(4-methoxyphenyl)-1,3,2,4-dithiadiphosphetane-2,4-disulfide with hydroxy substituted compounds (R-OH) gave rise to the formation of dithiophosphonate compounds 2. 3 and 4 [R-OH: N-(2-hydroxyethyl)-phthalimide, 1-(2-hydroxyethyl)pyridine and 2-(2-hydroxyethyl)pyrrolidine]. Compounds 3 and 4 have been shown in zwitterionic species. The 2,4-bis(4-methoxyphenyl)-1,3,2,4-dithiadiphosphetane-2,4-disulfide was reacted with 2-chloroethanol to give 4-methoxyphenyl-2-sulfido-1,3,2-oxathiaphospholane (5), synthesized by a new method. Nickel and Cadmium complexes (2a and 2c) of 1 were prepared. Compounds were characterized by elemental analysis, IR, (HNMR)-H-1, P-31-NMR, UV/VIS spectroscopies and crystal structure of 5 was determined.
